Answer:
C. jump discontinuity at x=-2
Step-by-step explanation:
At x=-2, you have to lift your pencil to keep drawing the graph. That means there's a jump discontinuity there.
This function has a jump discontinuity at x = -2.
__
<em>Additional comments</em>
At x=3, there is no discontinuity in the function. The <em>derivative</em> of the function has a discontinuity there, as there is an abrupt change in slope at that point.
If left and right limits exist and are the same at a point, but the graph is not defined at that point, then a <em>removable</em> discontinuity exists. All that is needed to fill the hole is to define the function at that point.
Answer:
Step-by-step explanation:
(x - 2) (3x + 1) (4x – 3)=
12x^3-29x^2+7x+6
Foil the binomials.
x*3x x*4x etc
Answer:
25
Step-by-step explanation:
3877 divided by 36 is 107.69. That means each person could get 107 masks (always round down in these problems)
36 time 107 is 3852, and 3877 minus 3852 is 25. This is how many will be left over.
