Question

Find the difference of functions s and r shown below. r(x) = –x² + 3x s(x) = 2x + 1

Answer 1

X^2-X+1

Explanation:

I understand this question is old, but the only answer provided is incorrect.

This question is off Edgen. Algebra II.

The answer choice for Edg. is the very last option.

(I would provide work but it is not required whatsoever and it's very annoying when you have to read 19 paragraphs just to get an answer)

Hope this helps any future algebra students!

Answer 2

This is the concept of algebra, we are required to get the difference between r(x)=-x^2+3x and s(x)=2x+1
thus;
r(x)-s(x)
=(-x^2+3x)-(2x+1)
=-x^2+3x-2x-1
=-x^2+x-1
the answer will therefore be:
r(x)-s(x)=-x^2+x-1
