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:
The value of a is 3
Step-by-step explanation:
First you have to make an equation based on the point and slope that you were given. The formula for this is y-(y cordinate of point)=slope(x-x cordinate of slope)
y--2=-3(x-6), which simplifies to y+2=-3(x-6)
In (a,7), 7 is the y coordinate. We have to plug 7 in for the y in our equation.
7+2=-3(x-6),
Combine like terms on the left side to get to 9=-3(x-6)
Multiply out on the left to get 9=-3x+18
Subtract 18 from the left side to get -9=-3x
Divide both sides by negative 3 to get 3=x (remember x is a)
8 is (7+4)/(7+4+5+9) = 11/25 = 0.44
9 is 5/(5+7) = 5/12 = 0.417 so I'm sorry I can't help with that one
I’m pretty sure the answer is c
