(08.07HC) An expression is shown below f(x)=5x^2+2x-3 Part A: what are the x-intercepts of the graph of f(x)? show tour work Part B: Is the vertex of the graph of f(x) going to be a maximum of 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 anwsers obtained in Part A and Part B to draw the graph.
