The value of g(x) is - 1.625.The function g(x) is used in place of any x in the function f wherever it appears.
<h3>Find the value of g(x)?</h3>
This area is between the graph of f(t) and the t-axis on the t-interval (0, 18), which is the preceding area MINUS the area of the polygon under the t-axis on the t-interval (9, 18), which consists of half of a 6x6 rectangle and a 6x3 rectangle.
For any two functions f and g, there can be two composite functions: f of g of x = (f ∘ g)(x) = f(g(x)) g of f of x = (g ∘ f)(x) = g(f(x)).
