If f(x) = x2 and g(x) = x - 3, then f(g(x)) = ?
10 months ago
Q:
If f(x) = x2 and g(x) = x - 3, then f(g(x)) = ?
Accepted Solution
A:
Please, use "^" to denote exponentiation:
If f(x) = x^2 and g(x) = x - 3, then f(g(x)) = ?
To answer this question, replace (x) in f(x) = x^2 with g(x) = x - 3. Then
f(g(x)) = (x-3)^2 - 3, or x^2 - 6x + 9 - 3, or f(g(x))= x^2 - 6x + 6 (answer)
