Question

Which function describes the range to be equal to four less than half of the domain? Question 3 options: f(x)=12(x−4) f(x)=4−12x f(x)=12(4−x) f(x)=12x−4

Answer 1

`f(x)=(1)/(2)x-4`

Explanation:

Given:

The range is 4 less than half of the domain.

The domain of a function is its input values represented by 'x'. The range of a function is its output values represented by 'y' values.

Domain is 'x'. So, half of domain is
`(1)/(2)x`.

Now, range is 4 less than half of domain. Hence,

`y=(1)/(2)x-4`

So, the correct option is the last option.
