If the composition of two functions is:
1/x-3

what would be the domain restriction? describe how you found that answer.
[no answer choices]
i'm pretty sure the answer would be x≠3, because typically in these scenarios, anything the x on the bottom is being subtracted by has that symbol and the number being subtracted from it. i believe this is because x is = to 3, meaning that - 3 would make it 0 again. thus, x≠3. but if this isn't true, i'd like someone else to explain it to me, and provide me with the correct answer.

R-{3}

Step-by-step explanation:

Given is a function

The domain is the possible values which x can take

Here on analysing the function we find that f(x) becomes undefined when denominator =0

i.e.

There cannot be any other restriction as there is no square root sign.

Hence domain is set of all real numbers except 3

In interval notation domain =

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
