Question

Match each function to the appropriate domain.
1. f(x)=3/(x-4)
2. f(x)=3x+2
3. Volume of a cube with side x
4. f(x)=sqrt(8-2x)

ANSWER CHOICES
a. all real numbers x!=4
b. x>0
c. All real numbers
d. x<=4

Determine the domain for f(x) given,
f(x)=sqrt(x+1)


SHOW EACH STEP in your work.
(thanks:)

Given the following piecewise function, find f(-5)
{3x + 2 for x <-3}
f(x)= {x+5 for x >(or equal to) -3}


Thank you so much!
