Question

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

Answer 1

A. The set of all real numbers less than 4

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.
