Question

If f(x) = -3 and g(x) = 3x²+x-6, find (+ Ø)(x). A. 3x²-x-3 B. 3x²+x-3 C. 3x²+x-9 D. 4x²-9​

Answer 1

Since f(x) = -3, we have (+ Ø)(x) = f(x) + g(x) = -3 + g(x)

Substituting g(x) = 3x²+x-6, we get:

(+ Ø)(x) = -3 + 3x²+x-6

Simplifying, we get:

(+ Ø)(x) = 3x²+x-9

Therefore, the answer is C. 3x²+x-9.
