Quadratic Functions, I can’t get past the factoring part
Use the function f(x) to answer the questions:
f(x) = 4x^2 − 7x − 15
: What are the x-intercepts of the graph of f(x)? Show your work.
: Is the vertex of the graph of f(x) going to be a maximum or a 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 and to draw the graph.
show your work, If you can only answer the first one that fine but explain very clearly
