g(r)=25 - 3r is an example of a function notation.

Note that g(4) is g(r) when r equals 4. Since r = 4, replace every r you see with 4 and then solve.

Work:
g(4) = 25 - 3(4) -> g(4) = 25 - 12 -> g(4) = 13

Answer: g(4) = 13; when r in g(r) equals 4, the value of our function would be 13.

Following are the calculation to the given function:

Given:

[tex]\bold{g(r)=25-3r}[/tex]

To find:

[tex]\bold{g(4)=?}[/tex]

Solution:

[tex]\to \bold{g(r)=25-3r}[/tex]

Putting the value r=4 into the above-given function:

[tex]\to \bold{g(4)=25-3(4)}\\[/tex]

            [tex]\bold{=25-3\times 4}\\\\ \bold{=25-12}\\\\ \bold{=13}\\\\[/tex]

So, the function value is "13".
