Should be S(1, -9) because you are rotating it 90 degrees which is 1/4 of 360 degrees.
The answer is C: multiply by 2
Answer: D
Step-by-step explanation:
Sometimes, it is hard to see which function fits g(x). We are given the point (4,1). Luckily, the point lies on g(x). We can plug in (4,1) into the g(x) equations and see which best fits.
A. Incorrect
![1=4(4)^2](https://tex.z-dn.net/?f=1%3D4%284%29%5E2)
