Based on the graph of an exponential function f(x)=b^x, for b >0, describe how you can verify that the output of the function can NEVER be equal to zero.

see the explanation

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

where

a is the initial value or y-intercept

b is the factor growth (b>0)

In this problem

a=1

so

we know that

The graph of the function has no x-intercept

Remember that the x-intercept of a function is the value of x when the value of the function is equal to zero

That means ----> The output of the function can NEVER be equal to zero

Verify

For f(x)=0

Apply log both sides

Remember that

log 0 is undefined. It's not a real number, because you can never get zero by raising anything to the power of anything else.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

its adding 5.5 each time
