Question

What is the domain of the function f(x)=x−16? f(x)=x−16?

The function is defined when f(x) is greater than or equal to 0, therefore the domain is f(x)≥0.
The function is defined only when x−16 is greater than 0, therefore the domain is x>16.
The function is defined for any value of x, therefore the domain is all real numbers.
The function is defined only when x is greater than or equal to 0, therefore the domain is x≥0.

Answer 1

C

Explanation:

f(x)=x-16 is just a straight line with a slope of one at a y intercept of -16. Therefore, x can hit all numbers in the x axis making the domain x is in the element of all real numbers.

Answer 2

all real numbers

Explanation:

literally the domain can be anything but the range is limited because of the vertical line check
