In Exercises 1–30, find the domain of each function. f(x)=3(x-4)

Question

Accepted Answer

Hello today we're gonna go ahead and find the domain of a given function. So the function given to us is F of X is equal to 17 times the quantity X minus 13. Now we can go ahead and simplify this function by distributing 17 into the quantity of X minus 13. Doing so is going to give us F of X is equal to 17, X minus 221. Now this is the equation of a line and a line has the domain of negative infinity to positive infinity. Because you can plug in any value of X into this function and any value of X is going to work with it. So that means that the domain again is going to be the set of all real numbers, which is negative infinity to positive infinity. And the answer to this problem is going to be D. So I hope this video helps you understanding how to find the domain of this given function. And I'll go ahead and see you all in the next video.
