Question 321936: What is the smallest integer that is NOT in the domain of the function below?
f(x)= sq. root of 4-x
If f(x) = x - 2, for what value of x does f (3x) = f(x+1)?
Evaluate t(y) = y3 + 64 if y = -4.

We can’t have a negative sign under the square root so 4-x must be positive or 0 if x is smaller than 4 then 4-x is positive, if x = 4 then 4-x is 0 so 5 is the smallest integer not in the domain
