Practice using Method 2 for the second problem. Let f (x) = x2 + 1 and g (x) = x - 2. Evaluate (g ∘ f) (0).

(g o f) (0) = -1

substitute the equation f (x) for the value of x in the equation g (x)

(g o f) (x) = (2x+1) - 2

Then substitute the given x value, 0

(g o f) (0) = (2 (0) + 1) - 2

(g o f) (0) = 1-2

(g o f) (0) = -1
