The first, third, and fourth choices are functions. A relation is a function when x does not repeat. For the second choice, -4 repeats. Therefore, it is not a function. The other choices do not repeat an x-coordinate, so they are correct.
No is the answer i believe
Answer:
1: x=2, 2: x=4, 3:x=3
Step-by-step explanation:
They are correct because i checked them
Answer: for the 12,13,40,95,88,7,95
mean 95,median 83,mode 95
Step-by-step explanation:
Given:
The inequality is

To find:
The value of x and then graph on the number line.
Solution:
We have,

Subtracting 19 from both sides, we get


It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
