Please show detailed work if possible-that will help me to better understand the questions start with this expression:
f(x) = 2x2 − x − 10

1st- What are the x-intercepts of the graph of f(x)? Show work on how to get this

2nd- Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Show work on how to get this

Part C: What are the steps you would use to graph f(x)? show how you can use the answers obtained in Part A and Part B to draw a graph
