In the exponential function f(x) = a * b^x, what does the 'a' represent?

• The base of the exponent

• The vertical shift

• The horizontal shift

• The vertical stretch or shrink

If the absolute value of 'a' is less than 1, what transformation occurs?

• Reflection across the x-axis

• Vertical shrink

• Horizontal shift

• Vertical stretch

What does the 'h' in the exponential function f(x) = a * b^(x-h) + k represent?

• Horizontal shift

• Vertical shift

• Reflection across the y-axis

• Vertical stretch

How does a positive 'h' value affect the graph of an exponential function?

• Shifts it to the right

• Shifts it to the left

• Moves it down

• Moves it up
