I need urgent help on this asap pls Use the function f(x) to answer the questions: f(x) = 4x2 − 7x − 15

Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)

Part B: 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. (3 points)

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)

Step-by-step explanation:

A: 4x2-12x+5x-15  check: 4(3)2-12(3)+5(3)-15=0 36-36+15-15=0 0=0 check: 4(-5/4)2-12(-5/4)+5(-5/4)-15 6.25+15-6.25-15=0 0=0 

4x(x-3)5(x-3)

(x-3)(4x+5)

x-3=0 4x+5=0

x=3 x=-5/4

this is just part a im working on part b and c now

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

it has changed from the width and the height.
