Question

Consider the parabola `y=x^(2)+7x+2` and the straight line `y=3x-3`.
The two parabolas `y^(2)=4ax" and "x^(2)=4ay` intersect
A. at two points on the line y = x
B. only at the origin
C. at three points one of which lies on y + x = 0
D. only at (4a, 4a)

Answer 1

Correct Answer - A
The parabolas `y^(2)=4ax" and "x^(2)=4ay`
They intersect at(0, 0) and (4a, 4a)
These points lie on `y=x`
