Here use general math mind
F(x) has more than one x inetercept .
- We shall take one quadratic function in which will give 2 intercepts(Real)
Domain is for real numbers
Four unique numbers?
- Add 4 constants for 4 unique definations and that shouldn't fall under quadratic region
Lets see
For -2
For 0 it's (0,0)
And for extra ,it's discontinuous on x=0
