Answer:
X=0
Step-by-step explanation:
Frst we want to check is it symmetry function?
F(-x)=f(x)?
We know that f(x)=x^2+0x-4=x^2-4.
What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!
Intesections with x is in the -2 and 2, so the middle is x=0.

Answer:
(4,5)
Step-by-step explanation:
Rotating a <em>point </em>by 90 degrees <em>counterclockwise</em> would make the y become x and switch it's negative/positive value, and make x the y.
Ex: (x,y) would become (-y,x)
