Question

Range of the function $y=3^{x+2}$ is-

• A. Set of real positive numbers
• B. Set of real negative numbers
• C. Set of real numbers
• D. None of the above

Answer 1

The correct option is A Set of real positive numbers

Given $y=3^{x+2}$

Here the domain of given function is $-\infty <x<\infty$

When $x=-\infty$ , then the value of $y$ is $0$

When $x=\infty$ , then the value of $y$ is $\infty$

So the range of given function is $(0,\infty )$ , which is set of real positive numbers

Therefore the correct option is $A$
