an expression is shown below:
f(x)=-16x^2+60x+16

part a: what are the x intercepts of the graph of f(x)? show your work. (2points)

part b: is the vertex of the graph of f(x) going to be a maximum of a minimum? what are the coordinates of the vertex? justifiy your answers and show your work.(3 points)

part c: what are the steps you would use to graph f(x)? justifiy that you can use the answers obtained in part a and part b to draw the graph (5 points)
