USA Test Prep: Review 1

SCORE: 

5. I did not multiply 20.5 x 30.5. I multiplied 20 x 30

9. I multiplied 36 by 75 instead of 3 x 75

 13. I didn't know how to do this problem 

 19. I was thinking of a smaller pool

Graphing Exponential Growth/Decay

GRAPHING EXPONENTIAL GROWTH/DECAY: 

y= aŸb^x-h+k

a= multiplier

         a>1 = stretch 
         0<a<1 = compression 
         a<0 (negative) = flipped over x-axis 
b= base 
         b>1 = GROWTH (always increasing)
         0<b<1 = DECAY (always decreasing) 
h= left/right (opposite) 
k= up/down
