Explanation
We are required to evaluate the following:
[tex]f(x)=\frac{1}{4}x\text{ }for\text{ }x=-5[/tex]This is achieved thus:
We substitute the value of x in the function as follows:
[tex]\begin{gathered} f(x)=\frac{1}{4}x \\ where\text{ }x=-5 \\ f(-5)=\frac{1}{4}\cdot(-5) \\ f(-5)=\frac{-5}{4} \end{gathered}[/tex]Hence, the answer is:
[tex]\frac{-5}{4}[/tex]
