Answer :
Question 2 :
f(x) = ax2 + 36x + c
g(x) = jx2 – 57x + ℓ
The functions f(x) and g(x) are both quadratic functions, and m is a positive constant. The parabola formed by the graph of y = f(x) has a vertex with a y-coordinate of 3m. The parabola formed by the graph of y = g(x) has a vertex with a y-coordinate of m. If f(10) = f(14) and g(-3) = g(27), for how many values of x does f(x) = g(x)?

A) Exactly one
B) Exactly two
C) Infinitely many
D) Zero
