Question

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y = 740(1.5) ^x

Answer 1

y= ab^x

if b>1 the function represents a growth

1.5>1, It represents a growth

Percentage rate of increase: (r)

1+r = 1.5

r= 1.5-1

r=0.5

0.5 x 100 = 50%
