Question

The life expectancy of a monkey is 15 years, an African elephant 35 years, a beaver 5 years, and a grizzly bear 25 years. Write a relation that describes this information. Determine its domain and range.

Answer 1

Answer:

The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35

Step-by-step explanation:

The given parameters are;

The life expectancy of a monkey = 15 years

The life expectancy of an African elephant = 35 years

The life expectancy of a beaver = 5 years

The life expectancy of a grizzly bear = 25 years

Therefore, if the  life expectancy of a beaver = X, we have;

The life expectancy of a monkey = 3 × The life expectancy of a beaver = 3·X

The  life expectancy of a beaver = X

The life expectancy of an African elephant = 7 × The life expectancy of a beaver = 7·X

The life expectancy of a grizzly bear = 5 × The life expectancy of a beaver = 5·X

Therefore;

The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35.
