Question

Find the domain of the function. Show all work.


1 if -9 < or = x<-7

f(x)= Abs(x) if -7 < or = x<9

Sq root(x)if 9 < or = x < or=35

Answer 1

Looks like the function is defined for all values of x in [-9,35]. That would be the domain.

It's a lot easier to read if you say

f(x) =
1 if -9 <= x < -7
abs(x) if -7 <= x < 9
sqrt(x) if 9 <= x <= 35
