Question

if f(x)=3x(2)-2 and g(x)=4x+2, what is the value of (f + g)(2)?

Answer 1

Answer:

Step-by-step explanation:

$f(x) = 3x^{2} - 2$

$g(x) = 4x + 1$

$(f + g)(x) = (3x^{2} - 2) + (4x + 1)$

$(f + g)(x) = 3x^{2} + 4x - 1$

$(f + g)(2) = 3(2)^{2} + 4(2) - 1$

$(f + g)(2) = 12 + 8 - 1$

$(f + g)(2) = 19$
