Answer: Choice B
{(0,0), (1,2), (2,4), (3,4)}
===============================================
Explanation:
A function is only possible if each x input leads to exactly one y output. For choice A, we have x = 1 lead to y = 3 and y = 5 at the same time, which is what the points (1,3) and (1,5) are saying. Therefore, choice A is not a function.
Choice C is also ruled out because x = 2 repeats itself as well. In this case, (2,3) and (2,4) means that the input x = 2 leads to the two outputs y = 3 and y = 4.
Choice D can be eliminated also for two reasons: x = 0 shows up twice, so does x = 2.
Only choice B has each x value listed one time only. So that means each input leads to exactly one output.
If you graph choice A, C or D, you'll find they fail the vertical line test. The vertical line test is where you test if you can draw a vertical line through more than one point on the graph. If you can draw a vertical line through more than one point on the graph, then the relation fails to be a function.

Answer:
(a) (6a - 3a) + (-3+6)
Step-by-step explanation:
Assuming "properly grouped" means that parentheses are placed around each group of terms, the appropriate choice is the one that groups 'a' terms and constant terms:
(6a - 3a) + (-3 + 6)
Answer:
-4
Step-by-step explanation:
-22-(6)(-9)/3
= -22 -(6) (-3)
= -22 +18
= -4
Answer:
<u>The age of Yessenia's father in terms of y is y + 32</u>
Step-by-step explanation:
1. Let's review the information provided to answer the question correctly:
Age of Yessenia now = y
Her father is 32 years older
2. What is the age in terms of y of her father?
If the age of Yessenia now is y, we can find out the age of her father, this way:
y + 32
<u>Therefore, the age of Yessenia's father in terms of y is y + 32</u>
