Question

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

Answer 1

`(s-r)(x)=x^2-x+1`

Explanation:

• So we subtract functions the same way we do numbers, ergo
• 
  `(s-r)(x)=s(x)-r(x)\\ (2x+1)-(-x^2+3x)\\2x+1+x^2-3x\\x^2+2x-3x+1\\(s-r)(x)=x^2-x+1`

Answer 2

There are 2 parts of the equation

The first answer to answer is (2x+1)--(-x2+3x)

The second answer is x2--x+1

I hope you have a wonderful day!!

Love you all!!
