What is g (r) = 25-3r?

solve for g (4)

g (4) = 13 is the answer

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.
