Find the difference of functions s and r shown below.
r(x) = -X2 + 3x
s(x) = 2x + 1
(s – r)(x) =

Answer & Step-by-step explanation:

In this problem, we are given two functions.

s(x) = 2x + 1

r(x) = -x² + 3x

We are asked to find the difference between s(x) and r(x).

(2x + 1) - (-x² + 3x)

Distribute the negative to the second parentheses.

2x + 1 + x² - 3x

Combine like terms and put the equation in standard form. This means the exponents should be in descending order.

x² - x + 1

So, (s - r)(x) equals x² - x + 1
