Question

Please help out!

Answer 1

\[f (x) = \sqrt{3x+4}\]

Answer 2

what would you like to know about this function?

Answer 3

How to solve it

Answer 4

domain? range? graph?
this is a function, not an equation. there is nothing to "solve"

Answer 5

Oh sorry, the domain

Answer 6

ah ok that is a question

Answer 7

you have a radical, and you have to make sure that the expression inside the radical is greater than or equal to zero, so solve
\[3x+4\geq 0\]
\[3x\geq -4\]
\[x\geq -\frac{4}{3}\] is your domain

Answer 8

you can write it as an interval is
\[[-\frac{4}{3},\infty)\]
