Question

Is the equation P = 500(1.03)n a model of growth or exponential decay?
A. Growth
B. Decay
What is the value of f(x) = 20 (2x) when x = 3?
A. f(3) = 120
B. f(3) = 64,000
C. f(3) = 160
D. f(3) = 80,000

Answer 1

growth because exponent is positive

Answer 2

when f(x)=20(2x) , just plug in the value put x=3
f(3) = 20(2*3)=20*6

Answer 3

So f(3) = 120 ??
