If you have the graph, the intersection of the 2 lines is the set of values that satisfy the equation (the x value is the answer)
I graphed useing desmos graphing to get the attached graph
the intersection points were
x=-2.78, 0.86, 2.91
the one that is the closest is none of them, I would go with the first one
The initial height of the ball is the y-intercept of the function
The initial height she threw the ball from is 35
<h3>How to determine the initial height</h3>
The function is given as:

Set x = 0.
So, we have:

Evaluate the exponent

Evaluate the products

Evaluate the sum

Hence, the initial height she threw the ball from is 35
