Exponential Decay and Growth

$y\ =\ \frac{1}{4}x-2$

$y\ =\ -\frac{1}{4}x+2$

$y\ =\ 2x\ +\ 4$

 $y\ =\ -3x-6\$  

 $y\ =\ -6x\ +\ 3$  

 $y\ =\ 3x\ +\ 6$  

 $y\ =\ \frac{1}{3}x+\ 6$  

 $y\ =\ 5x\ +\ 3$  

 $y\ =\ \frac{1}{3}x-5$  

 $y\ =\ 3x\ +\ 5$  

 $y\ =\ -\frac{1}{3}x+5$  

 $y\ =\ \frac{1}{3}x+2$  

 $y\ =\ \frac{1}{2}x\ -\ 3$  

 $y\ =\ -\frac{1}{2}x+3$  

 $y\ =\ 3x\ +\ \frac{1}{2}$  

Linear: $y\ =\ -3x\ +\ 2$

Linear: $y\ =\ -6x\ +\ 2$

Exponential: $y\ =\ \frac{1}{4}\left(2\right)^x$

Exponential:

$y\ =\ 2\left(\frac{1}{4}\right)^x$
