Question

Graph the function f(x) = 18(0.8)^x

options will be below

Answer 1

(0,18)

Explanation:

took the test

Answer 2

The graph in the attached figure

Explanation:

we have

`f(x)=18(0.8^(x))`

This is a exponential function of the form

`f(x)=a(b^(x))`

where

a is the initial value (the y-intercept of the function)

b is the base

r is the rate

b=1+r

In this problem we have

a=18

b=0.8

r=0.8-1=-0.2=-20% is a decay function
