3 sqrt(x) = 6

Question

g(x) = 2x/3

Answer 1

What is your question?

Are you solving the first one?

If so,....

3√x = 6
√x = 2

square both sides and you are done.

I don't know what you want done with g(x) = 2x/3

Answer 2

thanks, but for the 2nd one i'm not really sure how that is supposed to be solved.

Answer 3

Precisely my point.
You stated a function

g(x) = 2x/3 or
y = 2x/3

You can do several things with that:
1. graph it, it will be straight line
2. state the properties of the the resulting straight line
3. list a set of ordered pairs that satisfy the equation, (those are solutions, there would be an infinite number of correct solutions)

Since you did not specify what you want, I cannot help you with that part.

Answer 4

The second one merely states what the g(x) function IS. Plug in any x and calculate the corresponding g.

If you know g and want to know what x is, then
x = 3g/2
