Question

What is the range of the exponential function shown below?
f(x) = 9•2^x

Answer 1

i think the answer is y>0

Explanation:

Answer 2

Answer : y>0

f(x) = 9*2^x

f(x) is an exponential function

f(x) = 9*2^xf(x)=9∗2

x

When we plug in positive value for x , the value of y is positive

When we plug in negative value for x , the value y is also positive

So for any value of x, the y value is positive always.

Range is the set of y values for which the function is defined

y values are positive , so range is y >0
