Overview of exponential graphs

Which of the following is a characteristic of an exponential function?

• The exponent is a constant.

• The base is a variable.

• The function is always linear.

• The variable is in the exponent.

What is the range of a basic exponential function?

• From zero to one

• From negative infinity to positive infinity

• From zero to positive infinity

• From negative infinity to zero

What is the y-intercept of a basic exponential function A^x?

• (1, 0)

• (0, 0)

• (0, 1)

• (1, 1)

How does adding a constant outside the function A^x affect the graph?

• It changes the base of the function.

• It shifts the graph left or right.

• It reflects the graph over the x-axis.

• It shifts the graph up or down.

If the function is A^(x + h), what transformation occurs?

• The graph shifts h units to the left.

• The graph shifts h units to the right.

• The graph shifts h units up.

• The graph shifts h units down.

What happens to the graph of an exponential function when a negative sign is placed in front of the base?

• The graph shifts up.

• The graph reflects over the x-axis.

• The graph reflects over the y-axis.

• The graph shifts down.

Which transformation is represented by A^(-x)?

• Reflection over the x-axis

• Horizontal shift

• Reflection over the y-axis

• Vertical shift
