Question

What is the range of the exponential function shown below?

Answer 1

Answer:

Option B $y> 0$

Step-by-step explanation:

we have

$f(x)=9(2^{x})$

This is a exponential function of the form

$y=a(b^{x})$

where

a is the initial value

b is the base

r is the rate

b=1+r

In this problem

a=9

b=2

r=2-1=1=100%

The domain for x is the interval ------> (-∞,∞)

All real real numbers

The range is the interval -----> (0,∞)

$y> 0$

All real numbers greater than zero
