What is the definition of a function?
A function is a random assignment of outputs to inputs.
A function is a type of equation that does not relate inputs to outputs.
A function is a relation that assigns exactly one output for each input.
A function can have multiple outputs for a single input.
How do you determine if a relation is a function?
A relation is a function if each output can have multiple inputs.
A relation is a function if it has multiple outputs for the same input.
A relation is a function if it has no outputs for any input.
A relation is a function if each input has exactly one output.
What is the domain of a function?
The set of all possible input values for a function.
The range of a function.
The output values of a function.
The graph of a function.
What is the range of a function?
The set of all possible input values of a function.
The formula used to calculate the output of a function.
The set of all possible output values of a function.
The difference between the highest and lowest output values.
How do you find the inverse of a function?
Graph the function and reflect it over the line y=x.
Differentiate the function with respect to x.
Swap x and y, then solve for y.
Add 1 to the function's output.
What does the graph of a linear function look like?
The graph of a linear function is a curve.
The graph of a linear function is a circle.
The graph of a linear function is a zigzag line.
The graph of a linear function is a straight line.
What is the slope-intercept form of a linear equation?
y = b + mx
y = mx - b
y = m + bx
y = mx + b
How do you identify the vertex of a quadratic function?
The vertex can be found at (a, 0).
The vertex is always at the origin (0,0).
The vertex can be found at ( -b/(2a), f(-b/(2a)) ).
The vertex is located at (b, 0).
What is the significance of the x-intercepts and y-intercepts?
The x-intercepts show the maximum value of the function.
The x-intercepts indicate where the function equals zero, and the y-intercepts indicate the function's value when x is zero.
The y-intercepts indicate the slope of the function.
The x-intercepts represent the function's average value.
How do transformations affect the graph of a function?
Transformations do not change the graph at all.
Transformations only affect the color of the graph.
Transformations change the position, shape, and size of the graph of a function.
Transformations only change the graph's color and not its shape.
What is a piecewise function?
A piecewise function is a function that is defined by different expressions for different intervals of its domain.
A piecewise function is defined by a single expression for all values.
A piecewise function is a type of polynomial function.
A piecewise function is a function that is continuous everywhere.
How do you graph a quadratic function?
Graph a quadratic function by drawing a straight line through the origin.
Graph a quadratic function by plotting the vertex, y-intercept, and additional points, then drawing a parabola.
Use only the y-intercept to create a horizontal line.
Plot only the x-intercepts and connect them with a curve.
What is the difference between a continuous and a discrete function?
A continuous function has a finite number of values, while a discrete function has an infinite number of values.
A continuous function is always increasing, while a discrete function is always decreasing.
A continuous function is unbroken, while a discrete function consists of distinct, separate values.
A continuous function can only be defined on integers, while a discrete function can be defined on real numbers.
How do you find the asymptotes of a rational function?
Asymptotes can only be found graphically.
Vertical asymptotes are found by setting the numerator to zero.
Vertical asymptotes are found by setting the denominator to zero; horizontal asymptotes depend on the degrees of the numerator and denominator.
Horizontal asymptotes are always at y=0.
What is the relationship between a function and its derivative?
The derivative indicates the maximum value of the function.
The derivative of a function indicates how the function's output changes as its input changes.
The derivative measures the total area under the curve of the function.
The derivative of a function is the same as the function itself.
