Answer:
As we get closer to x=-3, the limit is approaches -1, on both sides of -3 so this is a good limit so c is 8.
Step-by-step explanation:
In order for a limit to exists, the left side limit must exist and right side limit must exist and on top of that, they must be equal to each other.
In this case, this a piece wise function and by definition of a limit that exist, the limit of this piece wise function as x approaches 3 from either side, must be equal.
We let x=-3 for the top equation.

So we set the second equation equal to -1.




So the value of c is 8. We can prove this by graphing as well.
Answer:
80
Step-by-step explanation:
Use the equation 180-(70 +30)
1/4 the probability of the 1st coin is 1/2 for landing on tails and for the second coin, the probability is 1/2 for it not to land on tails so u do 1/2* 1/2 and u get 1/4
The answer is -8 because -4x2 is -8
