2 . We can say that this function, h(x), was formed by the composition of two Examples – Now let's use the steps shown above to work through some –8x + 37. Example 2: If f(x) = –4x + 9 and g(x) = 2x – 7, find(g f)(x). Rewrite the Problem 1: If f(x) = x. 2. – 4x + 2 and g(x) = 3x – 7, find g)(x). (f. Problem 2: If g(x) = –6x + 5 

That is by calculating either f(x) or g(x). Example 1. Calculate the point of intersection of the two lines f(x) = 2x − 1 and g(x) = x + 1.
