1-130.
Let f(x) = x2 and
f(3)
f(−3)
g(9)
g(f(3))
g(f(6))
g(f(x))
f(3) = 9
Since f(x) and g(x) are inverse functions for x ≥ 0, g(9) = f(3) =______________
Recall that f(x) and g(x) are inverse functions for x ≥ 0, and the definition of an inverse function: f(g(x)) = x.
Because f(x) is even, f(−3) = f(3) = part a = _____
