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

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
