Question

Find the domain and range of f(x)=√(3x-7) -0.5

Answer 1

Any ideas?

Answer 2

Square root and domain,Oh well,always make sure that square root doesn't get a negative value,and move on.

Answer 3

this is the square root function

Answer 4

From the base graph

this is horizontally compressed by 1/3
moves right by 7 units
and down by 0.5

Answer 5

I know what it is I just don't know what brackets to use

Answer 6

are you sure the equation is not like

f(x) = √(3(x-7))-0.5

Answer 7

If its not you will have to factor out the 3 from x

Answer 8

yeah it is the one you just wrote

Answer 9

I messed up on the parentheses, sorry

Answer 10

Remembr the way I wrote is very important or else the whole thing changes

Answer 11

Ah got it

Answer 12

domain is xer|x>7

range is yer|y>-.05

is that what you got?

Answer 13

yeah it is
