Given that:
Worth of prepaid charge card = $15
Cost per ride = $1.50
Amount after each ride :
In solpe - intercept form:
Cost per ride = slope = 1.50
Intercept = $15
Amount left after each ride, f(x)
Number of ride, x
f(x) = 1.50x - 15

Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.
