4 people email 3 more people each so 12 people are emailed, then these 12 people email 3 more people each, so 36 people are emailed.
153=9*17=3*3*17
so the prime factorization is 3*3*17 (also can be written

*17)
Answer:
No, because a x-value repeats.
Step-by-step explanation:
A function has x-values that correspond to exactly one y-value. In the given table, <u>the number '5' appears twice as an x-value</u>. This means that the relation is not a function, "because one x-value corresponds to two different y-values."
The answer is C
The answer is C because the function form for a linear function is f(x) = ax+b and the answer C has x which is the slope and -3 which would represent the y-intercept also known as b
