F of G of X. To find f (g (x)), we just substitute x = g (x) in the function f (x). For example, when f (x) = x and g (x) = 3x - 5, then f (g (x)) = f (3x - 5) = (3x - 5) g (f (x)) = a function obtained by replacing x with f (x) in g (x). For example, if f (x) = x and g (x) = sin x, then (i) f (g (x)) = f (sin x) = (sin x) x whereas (ii) g (f ...Remember that the value of f' (x) anywhere is just the slope of the tangent line to f (x). On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f (x) = 5x + 1, then the slope is just 5 everywhere, so f' (x) = 5.Jul 7, 2022 Β· The function f(g(x)) represents the amount that Sonia will earn per hour by baking bread. What is a Function? A function assigns the value of each element of one set to the other specific element of another set. Given f(x)=9xΒ²+1 and g(x)=β(2xΒ³).

Example 4: f (x)=2x+4. g (x)= x+1. (fΓ·g) (x)=f (x)Γ·g (x) (fΓ·g) (x)= (2x+4)Γ·(x+1) The quotient of two functions calculator is especially designed to find the quotient value when dividing the algebraic functions..
