An expression is shown below.
f(x) = 4x2 + 8x - 5
part a: what are the x-intercepts of the graph of f(x)? show your work.
part b: is the vertex of the graph of f(x) going to be a maximum or minimum? what are the coordinates of the vertex? justify your answers and show your work
part c: what are the steps you would use to graph f(x)? justify that you can use the answers obtained in part a and part b to draw the graph.
