At how many points do the two graphs named as "First Graph" and "Second Graph" intersect?
1) The Equation of the first graph is x^2 + y^2 = 4
2) The second graph is a parabola with Y-Intercept -5

(A) Statement 1 alone is sufficient, but statement 2 alone is not.
(B) Statement 2 alone is sufficient, but statement 1 alone is not.
(C) Both statements together are sufficient, but neither alone is sufficient.
(D) Each statement alone is sufficient.
(E) Neither statement is sufficient, even when combined.

Hey Bunuel
Are Parabolic equations part of the GMAT?
I haven't seen any official question on the same.

In OG there is a chapter on coordinate geometry, where parabolas are discussed:
"The graph of a quadratic function is called a parabola and always has the shape of the curve above, although it may be upside down or have a greater or lesser width. Note that the roots of the equation \(f(x) = x^2 − 1 = 0\) are \(x = 1\) and \(x = − 1\); these coincide with the x-intercepts since x-intercepts are found by setting \(y = 0\) and solving for x. Also, the y-intercept is \(f( 0) = − 1\) because this is the value of y corresponding to \(x = 0\). For any function f, the x-intercepts are the solutions of the equation \(f( x) = 0\) and the y-intercept is the value \(f (0)\)."
Here is an official question on it: https://gmatclub.com/forum/for-what-val ... 11639.html
