Question

Domain and Range
f(x)= √3x+2

Answer 1

\[ {x \in \mathbb{R} : x \ge 0 }\]

Answer 2

Domain^

Answer 3

\[f \in \mathbb{R} : f \ge 2\]

Answer 4

range ^

Answer 5

then again maybe it is
\[f(x)=\sqrt{3x+2}\]

Answer 6

i should of put parenthesis around it huh? XD

Answer 7

@satellite73 your right

Answer 8

@zepdrix :D

Answer 9

yeah true
I did the domain & range based on:
\[f(x) = \sqrt(3 x)+2\]

Answer 10

sorry about that :X

Answer 11

@zepdrix help lol wth...

Answer 12

i know how to get Domain by setting the equation >_ to zero then solve. But how do you get the Range?

Answer 13

\[3x+2\geq =\iff 3x\geq -2\iff x\geq-\frac{2}{3}\]

Answer 14

for the domain

Answer 15

range is \([0,\infty)\) since the square root means the positive square root

Answer 16

always ?

Answer 17

and 0 is included?

Answer 18

yes, \(\sqrt{x}\geq 0\) always

Answer 19

zeros is included because the square root of zero is zero
