Question

The function f(x)=16sinx contains which type of transformation or change to its parent graph?
Phase shift
Vertical shift
Horizontal stretch or change in period
Vertical stretch or change in amplitude
And please explain how the transformations of the functions f(x)=15tanx and g(x)=tanx+15 differ.

Answer 1

16sinx has amplitude 16 instead of amplitude 1 like sinx has.

Answer 2

g(x)=tanx + 15 is tanx moved up 15
f(x)=15 tanx has a vertical stretch of 15
