What is the standard form of a linear function?

• y = a(b)^x

• Ax + By = C

• y = (a+1)^r

• y = x^2

How do you find the y-intercept from a graph of a linear function?

• It is where the graph crosses the x-axis

• It is where the graph goes flat

• It is where the graph crosses the y-axis

• It is the highest point on the graph

What is the result of increasing the slope of a linear function?

• Makes the line shift up

• Makes the line less steep

• Makes the line steeper

• Makes the line undefined

What is the vertex form of a quadratic function?

• y = x^2

• y = a(x-h)^2 + k

• y = ab^x

• Ax + By = C

How do you find the vertex of a quadratic function from its graph?

• It is where the graph crosses the y-axis

• It is the highest or lowest point on the graph

• It is where the graph crosses the x-axis

• It is where the graph goes flat

What does the 'a' value in the vertex form of a quadratic function indicate?

• The x-intercept of the graph

• The y-intercept of the graph

• The compression or stretch of the graph

• The shift of the graph along the x-axis

What is the exponential function formula?

• y = x^2

• y = a(b)^x

• Ax + By = C

• y = a(x-h)^2 + k

What does the domain of a function represent?

• The height from top to bottom of the graph

• The width from left to right of the graph

• The steepness of the graph

• The shift of the graph along the y-axis

What is the effect of multiplying the equation of an exponential function by a negative number?

• Causes a shift to the left

• Causes a shift to the right

• Causes a vertical stretch

• Reflects the graph across the x-axis

What is the effect of adding to the whole equation of an exponential function?

• Shifts the graph up

• Shifts the graph down

• Reflects the graph across the y-axis

• Causes a vertical compression
