Question

The function y=-0.04x^2+2x models the height of an arch support for a bridge, where x is the distance in feet from where the arch supports enter the water. How many real solutions does this function have?
A.0
B.1
C.2
D.3

Answer 1

I think it’s c because normally when the function touches the graph, the real solutions are based on the number of the exponent. Example, x^2= 2 real solutions...x^3= 3 real solutions
