12x+24≥0

12x≥-24

x≥-2

Hello

If you mean √(12x + 24)...

The domain is [-2 , +Inf[, as Jack said.

That function is monotone, increasing

So it is enough to find tha value of y at the lower limit of the domain :

When x = -2, f(x) = 0 and then increasing to infinity.

Therefore the range is [0 , +inf.[ or in other words y ≥ 0

If you mean (√12x) + 24

The domain is x ≥ 0

The function is also monotone increasing

For the lower value of the domain, f(0) = 24

Then the range will be y ≥ 24

So you see all depends on the brackets...

Hope it helps

It is fair to select a best answer, whatever it is. Thank you !
