f(x)=x^3. How do I find the domain and range? Please and thank you?

Answer 1

\[x \in R\]

Answer 2

Thank you.

Answer 3

WELCOME.........

Answer 4

in this case domain and range both are R

Answer 5

so if f(x)=x^4 would have the same answer, right?

Answer 6

IN THIS case domain is R

Answer 7

\[[0,\infty)\]

Answer 8

range is \[[0,\infty)\]

Answer 9

Thank you again. You're so much help.

Answer 13

can u please drawn it.......

Answer 14

ok

Answer 15

is it \[\sqrt{x+4}-2\] ??

Answer 16

\[f(x) equals \sqrt{x+4} -2\]

Answer 17

here domain is \[x+4\ge 0 \implies x \ge 4\]

Answer 18

sorry\[x \ge -4\]

Answer 19

range is R

Answer 20

Thank you. ^_^
