Question

If f(x) =x/2 -2 and g(x) = 2x2 + x - 3, find (8 +g)(x),

Answer 1

Answer: D) $2x^{2} +\frac{3x}{2} -5$

Step-by-step explanation:

$f(x)=\frac{x}{2} -2 \\g(x)= 2x^{2} +x-3\\\\\(f+g)(x)$

$\frac{x}{2} -2 +2x^{2} +x-3\\2x^{2} +\frac{x}{2} +x-5\\\\(f+g)(x)= 2x^{2} +\frac{3x}{2} -5$

Answer 2

I would go with D. 2x^2+3/2x-5
