Question

An expression is shown below: f(x) = 2x2 − 5x + 3 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 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)

Answer 1

Answer:

Step-by-step explanation:

A. f(x) = (2x-3)(x-1)

B. since the coefficient of x^2 is positive, the parabola opens upward.

C. plot the vetex, which is between the roots, at x = 5/4, plot the zeroes

plot the points at x=1,2, draw a curve through them.
