An expression is shown below:

f(x) = 16x²+ 60x + 16

Part A:What are the x-intercepts of the graph of the 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.
