Rewrite the function f(x) = 2(144) x/2 in the form f(x) = a(1+r)x. What are the values of a and r?

Question

a =
r =
When x increases by 1, the function increases or decreases by 20%, 50%, or 120%?

Answer 1

f(x) = 2(144) x/2
f(x) = 288x/2
f(x) = 144x

Therefore, a = 144 and r = 0.

When x increases by 1, the function increases by 20%.
