Question

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

Answer 1

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

I hope I helped you^_^

Answer 2

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