Graphing exponential and logarithmic functions

Does the following graph represent Exponential growth or decay?

• Growth

• Decay

What is the range of the exponential function represented by the graph above?

• y = ℝ

• y > -4

• y > -2

• y=-4

What is the RANGE of the function and how does it relate to the real-world context? (Click on the picture to make it larger!)

•  $y\le500$  The value of the computer is always $500 or less.

•  $y>0$  The value of the computer is always positive.

•  $0<y\le500$  The value of the computer is always more than $0 and no more than $500.

•  $y<500$  The value of the computer is always less than $500.
