You can move it up or down by adding a constant, call it c. Let c>0
Y=radical(x)+c move it up c and y= radical(x)-c moves it down c.
You can move it to the right by subtracting c inside the radical sign. Let c>0
y=radical (x-c) moves it to the right c units.
y=radical (x+c) moves it to the left c units.
Yes.
Yes.
Yes.
(a-2(ab)1/2+b)/(a-b)
It is a linear function passing through the origin. It represents a direct proportionality between x and y.
Sin2x = radical 2
No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
radical (64/3) or 8/sqrt(3)
4.89 roughly.
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30
It is sqrt(0), which equals 0.
yes. it is a function
