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

step-by-step explanation:

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
