What is the average rate of change of the function f(x)=5(2)^x from x = 1 to x = 5?

Find an equation of the line perpendicular to the graph.

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
