Question

What is the domain of the function f(x)=−12x+15? PLEASE HELP!!!

x≤30x≤30

x≥0x≥0

x≥−2x≥−2

all real numbers

Answer 1

Fourth option

Explanation:

Given the following question:


`f(x)=-12x+15`

The domain of a function is all possible x inputs for a function, on the contrary range of a function would be all possible y inputs for a function.


`f(x)=-12x+15`

Since the function has all defined points, it basically means that the functions possible x inputs are "all real numbers" or the fourth option.


`-\infty \: < x < \infty`

Hope this helps.
