Determine whether the equation represents y
as a function of x.
1. y = sqrt{x + 5}
2. ∣y∣ = 4 − x
@nycdad,
Y is a function of X if for every X there is only one value of Y. You should be able to look at the two equations below and see that that is true in one, not in the other.
@engineer,
Ok. I get it now. I will solve these two problems on paper and return to further discuss this idea if needed.
