Question

What is the range of f(x)= -3^x+4

Answer 1

Answer:

A. The set of all real numbers less than 4

Step-by-step explanation:

The range of the parent function $y=3^x$ is $y\in (0,\infty)$

The graph of the function $y=-3^x$ is reflected across the x-axis graph of the parent function, so the range of the function $y=-3^x$ is $(-\infty,0)$

The graph of the function $y=-3^x+4$ is translated 4 units up graph of the function $y=-3^x$, so the range of the function $y=-3^x+4$ is $(-\infty,4)$ or the set of all real numbers less than 4.
