Unit 0-1 Practice For Test

Front

What is the value of x if f(x) = -2?

Back

x = 8

Front

What is f(1) if f(x) = 5?

Back

f(1) = 5

Front

Write an equation to show the relationship between the stage number, x, and the number of squares if the pattern models a quadratic relationship.

Back

y = 3x^2

Front

How do you find the rate of change (slope) of a line?

Back

The slope is the change in y over the change in x. For this case, the slope is 4.

Front

What is the domain and range of the function represented by the graph?

Back

Domain: -2, -1, 0, 1; Range: -1, 0, 1, 2

Front

Define a quadratic function.

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax^2 + bx + c.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

What does the vertex of a parabola represent?

Back

The vertex of a parabola represents the maximum or minimum point of the quadratic function.

Front

How do you determine the x-intercepts of a quadratic function?

Back

Set f(x) = 0 and solve for x using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a.

Front

What is the difference between domain and range?

Back

Domain refers to all possible input values (x-values) of a function, while range refers to all possible output values (y-values).
