PLEASE HELP IF YOU HELP ILL VOTE YOU BRAINIEST f(x) = 2x2 + 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.

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem.
