The required function of function f(g(x)) = 3x2 + 15x + 15.
f(x) = 3x - 6
g(x) = x2 + 5x + 7
f(g(x)) to be determined.
What are functions?
Functions are the relationship between sets of values. e g y=f(x).
f(x) = 3x - 6
g(x) = x^2 + 5x + 7
Now the function of function
f(g(x)) = 3(x^2 + 5x + 7)-6
= 3x^2+15x+21-6
= 3x^+15x+15
Thus, The required function of function f(g(x)) = 3x2 + 15x + 15.
