Where is the vertex of f(x) = -2x - 3| +6.4?

Acable car begins its trip by moving up a hill. as it moves up, it gains elevation at a constant rate of 50 feet/minute until it reaches the peak at 2,000 feet. then, as the car moves down to the hill’s base, its elevation drops at the same rate.

Match each function with the corresponding function formula when h(x)=5-3x and g(x)=-3+5
