Answer:
[-1,6)U(6, ∞)
Step-by-step explanation:
In functions that have a square root, the radicand (the inside of the root) has to be ≥0. Otherwise, you would be dealing with imaginary numbers.
So, in our function,
We have two factors in our denominator. Note that you cannot divide by 0. So to find where x <em>cannot </em>be, we have to set the denominator to 0.
X cannot be either -4 or 6.
So, x has to be greater than or equal to -1 and cannot equal -4 or 6.
x≥-1, x≠6
If you use the X symbol on you calculator, the one and only accurate answer would be 4 in this situation, you could just say 2 plus 2 and you get the same answer!
hope this helped you in the future! ;)
H^2=x^2+y^2
35^2=29^2+y^2
y^2=35^2-29^2
y^2=384
y=√384
y≈19.60 m (to the nearest hundredth of a meter, or nearest centimeter)
Answer:
function, is that ome to many relation?
Step-by-step explanation:
every y value have a exact x value mapped onto it
