Answer: Domain: x ≥ 0 Interval Notation: x = [0, ∞)

Step-by-step explanation:

f(x) = 3√x

There IS a restriction on x because it is inside the square root symbol.

In order for the radical to be a real number, the expression under the radical must be greater than or equal to 0. The value inside the radical is "x".

So, x ≥ 0 It is already solved for x so no further work is needed.

Matttttttttttttttttthhhhhhhhhh , HELLPPP !

Harman [31]

here we have 3X to 5 seventh power in radical form

$3x^{5/7}$

we need write this in radical form we knwo that $x^{1/2} =\sqrt{x}$

so $3x^{5/7} =\sqrt[7]{3x^{5}}$

this will be the radical form .

Subtract 7x-9 from 2x^2-11 A) 2x^2-7x-2 B) 2x^2+7x-20 C) 2x^2+7x-2

Natali [406]

We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.

Answer:

The inequality for this would be n ≥ 20.

We know this because it must be larger than 40. We also know it can possibly be equal because the statement says "at least".
