Write the composition function and then find the value.
f(x) = 2x+3
g(x) = x^2
k(x) = square root(x - 4)
1. g(k(x))
g(k(20))
My answer: Function is x - 4, the value is 16.
2. f(g(x))
f(g(2))
My answer: Function is 2x^2 + 3, the value is 11.
f(x) = 2x+3
g(x) = x^2
k(x) = square root(x - 4)
1. g(k(x))
g(k(20))
My answer: Function is x - 4, the value is 16.
2. f(g(x))
f(g(2))
My answer: Function is 2x^2 + 3, the value is 11.
