Describe the transformation required to obtain the graph of the given function from the basic inverse trigonometric
graph.
-$$f ( x ) = \sin ^ { - 1 } 7 x$$
A) Horizontal shrink by a factor of $\frac { 1 } { 7 }$
B) Horizontal stretch by a factor of 7
C) Vertical translation up 7 units
D) Vertical stretch by a factor of 7

Question

Quizplus · Accepted Answer

The transformation required is a horizontal shrink by a factor of $\frac{1}{7}$, because the coefficient 7 inside the function affects the x-values directly, making the graph compress horizontally.
