Answer:
r(s(-2)) = -2
Step-by-step explanation:
We are given these following functions:
![r(x) = -2x + 2](https://tex.z-dn.net/?f=r%28x%29%20%3D%20-2x%20%2B%202)
![s(x) = x^2 - 2](https://tex.z-dn.net/?f=s%28x%29%20%3D%20x%5E2%20-%202)
Find the value of r(s (-2)).
First we find the composition of r and s functions. It is:
![r(s(x)) = r(x^2-2) = -2(x^2-2) + 2 = -2x^2 + 6](https://tex.z-dn.net/?f=r%28s%28x%29%29%20%3D%20r%28x%5E2-2%29%20%3D%20-2%28x%5E2-2%29%20%2B%202%20%3D%20-2x%5E2%20%2B%206)
At x = -2
![r(s(-2)) = -2(-2)^2 + 6 = -8 + 6 = -2](https://tex.z-dn.net/?f=r%28s%28-2%29%29%20%3D%20-2%28-2%29%5E2%20%2B%206%20%3D%20-8%20%2B%206%20%3D%20-2)
r(s(-2)) = -2
1 - 0.16 = 0.84
21/0.84 = 25
