Answer:

2x^2 +11

Step-by-step explanation:

f(x) = 3x^2 + 2 and g(x) = x^2 – 9

(f – g)(x) = 3x^2 + 2 -( x^2 – 9)

Distribute the minus sign

3x^2 + 2 - x^2 + 9

Combine like terms

2x^2 +11

w < 7

Step-by-step explanation:

Since the sign is going to the left that means it's < or ≤

The one that has both of these effects is <

Since the sign starts at 7, the inequality is w < 7
