Consider the function below, f (x) =x^3 + 2x^2-x-2, plot x- and y- intercepts of the function

The x-intercepts are at x = -2, x = -1, and x = 1.

The y-intercept is at y = -2.

Step-by-step explanation:

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

x   y  

-3  -8

-2   0

-1   0

0  -2

 1   0

(b) Plot the points on your graph

They should look something the graph below.  

The x-intercepts are at x = -2, x = -1, and x = 1.

The y-intercept is at y = -2.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
