Q:
# 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

Accepted Solution

A:

Let's solve for a.y=2x2+3andgxStep 1: Flip the equation.3adgnx+2x2=yStep 2: Add -2x^2 to both sides.3adgnx+2x2+β2x2=y+β2x23adgnx=β2x2+yStep 3: Divide both sides by 3dgnx.β3adgnx3dgnxβ=ββ2x2+y3dgnxβa=ββ2x2+y3dgnx answer :a=ββ2x2+y3dgnx
