Question

If (x) = x/2 -3 and g(x) = 3 x 2 + x - 6 , find (f+g) (x)

Answer 1

I believe it’s -12x but I may be wrong I hope this helped!

Answer 2

Answer:

$(f + g)(x) = ( \frac{x}{2} - 3) + (3 {x}^{2} + x - 6) \\ \\ = 3 {x}^{2} + (\frac{x + 2x}{2} ) - 9 \\ \\ = 3 {x }^{2} + \frac{3x}{2} - 9$

I hope I helped you^_^
