\(\large\color{black}{ \displaystyle f(x)=-5x }\) when you compress the function vertically by 1/a, you divide by a: \(\large\color{black}{ \displaystyle f(x)=-(5/a)x }\) and when you reflect across the x-axis, you multiply the entire function times -1.

just mutliply the function times -1, and tell me the answer.

\(\large\color{black}{ \displaystyle f(x)=-5x }\) when you compress the function vertically by 1/4, you divide by 4: \(\large\color{black}{ \displaystyle {~~~~~~~~}=-(5/4)x }\) and when you reflect across the x-axis, you multiply the entire function times -1. \(\large\color{black}{ \displaystyle {~~~~~~~~}=(5/4)x }\)
