Question

If f(x) = 2x2 + 3x and g(x) = x – 2, what is (f + g)(2)?

Answer 1

$\text{Solve the expression}\\\\\text{First, add the expressions together:}\\\\2x^2+3x+x-2\\\\2x^2+4x-2\\\\\text{Plug in 2 to x:}\\\\2(2)^2+4(2)-2\\\\\text{Solve:}\\\\2(2)^2+4(2)-2\\\\2(4)+4(2)-2\\\\8+8-2\\\\16-2\\\\14\\\\\boxed{\text{Answer: B).14}}$
