Answer:
Step-by-step explanation:
(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply
(4a - 3)(a + 1) = 39(3b + 1)
4a^2 + a - 3 = 117b + 39
4a^2 + a - 42 = 117b
b = 
Do this by converting to vertex form
y = 4x^2 + 16x - 2
y = 4 (x^2 + 4x - 0.5) completing the square on x^2 + 4x:-
y = 4[(x + 2)^2 - 4.5]
the axis of symmetry is x = -2
