An expression is shown below: f(x) = 2x2 + 5.0 - 3

Part A: What are the x-intercepts of the graph of f(x)? Show your work factoring and using the Zero Product
Property.

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 using the vertex formula.

Part C: Identify the point of the y-intercept for f(x).

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

b. the decimal could be two-tenths.

step-by-step explanation:

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
