Question

Determine the range for the following where c is in the stated domain:

D. y = 5 where 10 < x < 20

Answer 1

For the constant functionf(x)=c, the domain consists of all real numbers; there are no restrictions on the input. The only output value is the constant c, so the range is the set {c} that contains this single element.

Explanation:

Answer 2

Range={5}

Explanation:

The range of a function is the set of all possible outputs of the function.

In this case:

The function is y = 5

The domain is 10 < x < 20.

Since the value of y is always 5, the range is also a set of one value: {5}.

Therefore, Range={5}
