Can someone give me a refresher on this?

Let 𝑓(𝑥) = 4𝑥 + 1 𝑎𝑛𝑑 𝑔(𝑥) = 2𝑥
2 − 3 . Find (𝑓 − 𝑔)(𝑥)

Answer 1

(f-g)(x) just means subtract

f(x) - g(x)

Answer 2

a) −2𝑥^2 + 4𝑥 + 4
b) −2𝑥^2 + 4𝑥 − 4
c) 2𝑥^2 − 4𝑥 + 2
d)
2𝑥^2 − 4𝑥 + 4

Answer 3

so it ends up being

4x + 1 - 2x^2 + 3

Answer 4

combine like terms

Answer 5

−2𝑥^2 + 4𝑥 + 4
correct?

Answer 6

very good
