Given the function:
[tex]f(x)=15x+25[/tex]You need to substitute the following value of "x" into the function:
[tex]x=\frac{1}{5}[/tex]And then evaluate, in order to find:
[tex]f(\frac{1}{5})[/tex]Therefore, you get:
[tex]f(\frac{1}{5})=15(\frac{1}{5})+25[/tex][tex]f(\frac{1}{5})=\frac{15}{5}+25[/tex][tex]\begin{gathered} f(\frac{1}{5})=3+25 \\ \\ f(\frac{1}{5})=28 \end{gathered}[/tex]Hence, the answer is:
[tex]f(\frac{1}{5})=28[/tex]
