1. i know it might look easy for some people but i am actually struggling
how do you find the point of intersection of y=4-x² and y=3x
2. here is a hint:
3x2=6
3+3=6
3x2=3+3

Take equal the right side of equations and solve x
4. If you have two equations in the same form, y = blah1 and y = blah2, then you know when they meet the Y value will be the same, so if you put them equal to each other, you can solve to find the x value.

EG,
4-x^2 = y = 3x
4-x^2 = 3x
x^2 + 3x - 4 = 0

and then you can solve like a normal quadratic and substitute back in to find the y values.
