Writing and interpreting exponential functions

Write the equation of the graph.

• f(x) = 3^x+2

• f(x) = 3^x - 2

• f(x) = 3^x + 2

• f(x) = (1/3)^x +2

Which equation matches the graph?

• y = 2^x+3
• y = 2^x + 3
• y = 2^x
• y = 2^-x

Create an equation for the exponential function above. (Click on the image to zoom in).

• y = 4(2)^x - 5

• y = -1(0.5)^x + 3

• y = -4(2)^x + 3

• y = 4(-2)^x - 3

What is the equation of the graph shown?

• f(x) = 4(1/2)^x

• f(x) = 4(2)^x

• f(x) = 4(1/3)^x

• f(x) = 4(3)^x

Which equation matches the graph?
