Question

Let f(x) = x + 2 and g(x) = x2 – 6x + 3. Find g(f(x)).

Answer 1

This is saying that wherever there is an 'x' in the g(x) function, sub in the function f(x).
So: \[(x+2)^{2} - 6x + 3\]
Final answer:
\[x ^{2} - 2x +7\]

Answer 2

x2 - 2x - 5

Answer 3

You also plug it into "6x"

Answer 4
