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.

Solve the equation by completing the square. x^2+2x=17

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
