Answer:
A. The set of all real numbers less than 4
Step-by-step explanation:
The range of the parent function [tex]y=3^x[/tex] is [tex]y\in (0,\infty)[/tex]
The graph of the function [tex]y=-3^x[/tex] is reflected across the x-axis graph of the parent function, so the range of the function [tex]y=-3^x[/tex] is [tex](-\infty,0)[/tex]
The graph of the function [tex]y=-3^x+4[/tex] is translated 4 units up graph of the function [tex]y=-3^x[/tex], so the range of the function [tex]y=-3^x+4[/tex] is [tex](-\infty,4)[/tex] or the set of all real numbers less than 4.
