(QUESTION) 3.11

What is (f−g)(x)?



f(x)=3x5+6x2−5

g(x)=2x4+7x2−x+16



Enter your answer in the box.

(f−g)(x)=

Answer 1

3x^5 − 2x^4 − x^2 + x − 21

This is the correct answer! I just took the test! Good luck!

Answer 2

`\bf 3x^5-2x^4-x^2+x-16`

Explanation:

`\bf (f-g)(x)=f(x)-g(x)=3x^5+6x^2-5-(2x^4+7x^2-x+16)=3x^5+6x^2-5-2x^4-7x^2+x-16=\\\\=3x^5-2x^4-x^2+x-16`
