Classify the relations according to whether or not they are functions.

Dvinal [7]

First of all, let's explain the term relation. Many everyday phenomena involve two quantities that can be related to each other by some rule of correspondence. In mathematics the term for such a rule of correspondence is called relation. Relations are often represented by mathematical equations and formulas.

Suppose you have a set A and a set B, so if a relation assigns to each element $x$ in the set A exactly one element $y$ in the set B, then the function $f$ is in fact that relation.

Ngozi earns $24000 in salary in the first year she works as an interpreter. each year, she earns a 3.5% raise.

Novosadov [1.4K]

Given that the current salary for Ngozi is $24000 and she earns 3.5% raise yearly, the function that will represent her salary in t years will be:
A=P(1+r)^t
where:
A=future amount
P=principle
r=rate
t=time
thus plugging in the values we shall have:
s(t)=24000(1+3.5/100)^t
s(t)=24000(1.035)^t
thus the answer is:
s(t)=24000(1.035)^t
