Answer:
(f - g)(2) = 13 - (-1) = 14
Step-by-step explanation:
Please write f(x) = 3х2 +1 as f(x) = 3х^2 +1; use " ^ " to represent exponentiation.
We could either find the new function (f - g)(x) first and then substitute 2 for x, or we could evaluate both f and g at x = 2 and then subtract the results.
f(2) = 13 and g(2) = -1, so (f - g)(2) = 13 - (-1) = 14
