Answer:
10/3 ..don't trust I might be wrong
Wish I could help on so sorry
if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation

now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
150 divided by 25 equals 6. 6 times 3 equals 18. This means that you will spend $18 on gas each week.
