You need the Law of Sines for this. In our case we have the measure of angle B and side b, we have the measure of angle A and are looking for side a, or x. Setting up the Law using our info, we have

. We will solve for x by multiplying both sides by sin(42):

, first choice above.
F(x) = (x^2) + x + C at (1,1)
1 = 1 + 1 + C
-1 = C
so,
F(x) = (x^2) + x - 1
