Answer:
D. x^2 + 2x - 25
Explanation:
The y-intercept is -25, eliminating choice C. The axis of symmetry is negative, eliminating choices A and B. (The axis of symmetry is x = -b/(2a), so the coefficient of x must be positive for a negative axis of symmetry.)
The only viable choice is D:
x^2 + 2x - 25
_____
Additional comment
Though the y-intercept is in the right place, it seems to me the vertex and x-intercepts are slightly too far left for the given equation. That is why I chose to eliminate non-viable answers, rather than try to determine the equation directly. That is also why I elected to show a better graph of equation D.
