F (x) = 2x^2 + 3 and g (x) = x^2 - 7, find (f-g) (x)

A) 3x^2 - 10

B) x^2 - 4

C) x^2 + 10

D) 3x^2 - 4

Let's solve for a. y = 2 x2 + 3a n d g x Step 1: Flip the equation. 3a d g n x + 2 x2 = y Step 2: Add - 2x^2 to both sides. 3a d g n x + 2 x2 + - 2 x2 = y + - 2 x2 3a d g n x = - 2 x2 + y Step 3: Divide both sides by 3dgnx. 3a d g n x 3d g n x = - 2 x2 + y 3d g n x a = - 2 x2 + y 3d g n x answer : a = - 2 x2 + y 3d g n x
