Question

If f(x) = 3x^5 + 4x^4 + 5, then what is the remainder when f(x) is divided by
X + 3?

Answer 1

remainder: -400

Step-by-step explanation:

`\sf f(x) = 3x^5 + 4x^4 + 5`

divided by x + 3

• x + 3 = 0

• x = -3

insert x = -3 in the function

`\sf f(x) = 3(-3)^5 + 4(-3)^4 + 5`

`\sf f(-3) = -400`
