Answer:
A
Step-by-step explanation:
for the relation to be a function then each value of x in the domain must map to exactly one unique value of y in the range
this is the case for A
in B : 3 → 2 and 3 → 8 ← not a function
in C : - 2 → 5 and - 2 → 7 ← not a function
in D : 2 → 2 and 2 → 3 and 3 → 3 and 3 → 2 ← not a function
Answer:
B
Step-by-step explanation:
The measure of the frequency of exposure is how often the target audience is exposed to a communication within a specified period of time. In this case it was aired only once and reached 500 million viewers even though in later years it was aired also on other television programs
When each x value has only one y value, the relation is a function
We know that coefficient of an equation is the number multiplied by variable.
-8 and 1.5 are the constants for our given equation.
The variable of our given equation is x. We can also see that x is being multiplied by 0.5, therefore, 0.5 would be the decimal coefficient of our given equation.
