Question

Question: An expression is shown below: f(x) = x^2 – 6x + 5

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

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.

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.

Answer 1

x-int > 1 and 5

vertex > 3,4

maximum

Explanation:

1. you have to factor the equation

(x-1)(x-5) > xint is 1 and 5
