Answer:
or 
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to

where
a is a coefficient
x_1 and x_2 are the roots or x-intercepts of the quadratic equation
In this problem we have

substitute

<em>Find the value of a</em>
we have the y-intercept (0,37.8)
substitute the value of x and the value of y of the y-intercept in the equation and solve for a


so

Convert to expanded form
