Question

Given f(x) = .5(50 + x), what is the value
of f (25)?

Answer 1

f(25)= 37.5

Explanation:

Here you would start the equation by substituting x for 25 everywhere.

so it would be

f(x) = 0.5(50+25) would turn into f(25) = 0.5(50+25)

first you would do the parenthesis as according to pemdas and its easier.

f(25) = 0.5(75)

then you would multiply 0.5 and 75 which equals 37.5

so

{f(25) = 37.5}
