Question

what will be the domain of (x+3)^1/3 plx tell me

Answer 1

is 1

Answer 2

tell me plx the answer of one question I have a quiz tomorrow

Answer 3

how its domain is 1

Answer 4

multiple 1/3 by x and 1/3 by 3 and x = 1

Answer 5

Hold on, chrome crashed.

Answer 6

ok

Answer 7

First let
\[y=(x+3)^{1/3}\]
That's equivalent to
\[\LARGE y=\sqrt[3]{x+3}\]
To find the domain set y=0,
\[0=x+3\]
x=-3
Now we have "x greater than or equal to" (because it's positive values) -3 the values starts from -3 to infinity. These are real numbers also.

Answer 8

so its domain would be all real number excepy -3?

Answer 9

Nope, the domain will includes all the values greater than or equal to -3, which means
\[\left\{ x \in \mathbb{R} : x \geq -3 \right\}\]

Answer 10

include*

Answer 11

ok thank u

Answer 12

I have a one question plx solve it
find the formulas for f+g,f-g,fg,f/g and domain of the function
f(x)=2(x-1)^1/2 and g(x)=(x-1)^1/2

Answer 13

^ 1/2 means under root

Answer 14

just valus in bracket is in under root

Answer 15

Its easy, for f+g, it means
\[f(x)+g(x)\]
\[\large 2(x-1)^{1/2} \color{red}{+} (x-1)^{1/2}\]
--------------------------------------
For f-g,
\[f(x)-g(x)\]
\[\large 2(x-1)^{1/2} \color{red}{-} (x-1)^{1/2}\]
--------------------------------------
For fg,
\[f(x) \times g(x)\]
\[\large 2(x-1)^{1/2} \color{red}{\times } (x-1)^{1/2}\]

Answer 16

ok thank you and how can we find its domain
I have problem in finding domain
we will find separate of each?

Answer 17

ok

Answer 18

i have problem in finding domains

Answer 19

what will be domain of 1-x

Answer 20

That would be all real because there is no restrictions
