Question

If ƒ(x ) = x 2 + 1 and g(x ) = 3x + 1, find ƒ(2) + g(3).

5/3
12
15
what is the answer

Answer 1

Evaluate the function f at 2 and the function g at 3. Then add the results.

\(f(x) = x^2 + 1\) and \(g(x) = 3x + 1\)

\(f(2) = 2^2 + 1\) and \(g(3) = 3(3) + 1\)

\(f(2) = 4 + 1 = 5\) and \(g(3) = 9 + 1 = 10\)

\(f(2) + g(3) = 5 + 10 = 15\)
