For this question: find gof:
f: R ---> R and g: R ---> R given by f(x) = 2x -5 and g(x) = 5x +2
I've done my working out and would like to know if this is correct.
(fog)(x) = f(5x+2)
(fog)(x) = 2(5x+2)-5
(fog)(x) = 10x+4-5
(fog)(x) = 10x-1
Is that all I need to do for this question and is what I've done right?
The R's obviously mean real numbers.
