Question

The graph of f(x)=20(0.5)x is shown.

Which statement about the function is false?

a.The average rate of change over the interval [0, 2] is -7.5.


b.The horizontal asymptote is at y = 0.


c.f(2) = 5


d.As x increases, f(x) increases.

Answer 1

C) f(2) = 5

Explanation:

f(2) = 20(0.5)*2

f(2) = 2(10)

f(2) = 20

f(2) = 20 ≠ f(2) = 5
