An expression is shown below:
f(x)=2x^2+5x−3
Part A: What are the x-intercepts of the graph of f(x)? Show your work factoring and using the Zero Product Property.
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 using the vertex formula.
Part C: Identify the point of the y-intercept for f(x).
Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A, Part B, and Part C to draw the graph. Draw the graph.
