Question

What is the domain and range of each function?

Answer 1

Answer:

Greetings!

A) Domain: x∈R or in interval notation (- ∞, ∞)

Range: x∈R or in interval notation (- ∞, ∞)

Thus, they both the domain & the range of the first function are the same.

B) Domain: x∈R or in interval notation (- ∞, ∞)

Range: [-5,∞)

Answer 2

Using it's concepts, the domain and the range of the functions are given as follows:

a) Both all real numbers.

b) Domain all real numbers, range $y \geq 5$.

What are the domain and the range of a function?

• The domain of a function is the set that contains all the values of the input.

• The range of a function is the set that contains all the values of the output.

In this problem, neither function has any impediment, such as an even root or denominator, hence the domain is all real numbers. As for the range, a linear function assumes all real values, while a concave up quadratic function assumes values of the vertex, in this case y = 5, and greater, hence the range of the second function is $y \geq 5$.
