Does this data show exponential or linear behavior? What's the equation?

• linear, $y=5x+5$

• exponential, $y=5^x$

• linear, $y=\frac{1}{5}x+1$

• exponential, $y=2^x+5$

Does the data show exponential or linear behavior? What's the equation?

• exponential, $y=3^x$

• linear, $y=3x+3$

• linear, $y=9x+9$

• exponential, $y=9^{-x}+27$

Does the data show linear or exponential behavior? How can you tell?

• exponential, each y term is the previous one multiplied by 0.5

• linear, the x terms are increasing by 5 each time

• exponential, $y\div x$ is always the same

• linear, $x+y$ is always the same

This is an example of....

• an increasing exponential function

• a decreasing exponential function

• an increasing linear function

• none of the above
