Graph the function f(x)=x^2-4x - 5 on the coordinate plane.
(a) what are the x intercepts?
(b) what is the y intercept?
(c) what is the maximum or minimum value?

(a) (-1, 0) and (5, 0)

(b) (0, -5)

(c) (2, -9)

Step-by-step explanation:

f(x) = x² - 4x - 5  

(1) Create a table containing a few values of x and y

x   y  

-1     0

0   -5

1    -8

2    -9

3    -8

4    -5

5     0

(2) Plot your points

Draw markers (dots?) at the coordinates of each point.

(3) Draw the graph

Draw a smooth line through the points.

Extend the line in both directions to the edges of the plot area.

Your graph should look like the figure below.

(a) x-Intercepts

The x-intercepts are at (-1, 0) and (5, 0).

(b) y-Intercept

The y-intercept is at (0, -5).

(c) Minimum

The minimum is at (2, -9).

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

c

-by-step explanation:

it would be c
