Question

Heya Guys!!!

Where Radical function will be zero??

Answer 1

Finding the zeros is another way of saying finding the roots. Finding the zeros of radical functions is unique because sometimes the roots that we find do not actually satisfy the function. These roots are called extraneous zeros.

The strategy for finding roots of radical functions is to isolate the radical expression and then square both sides to solve for x. In doing this, we square a quantity which will get us the same result if we square its opposite, which does not satify the original function. Like we observed before in the first three examples, the equation we ended up with when we solved for both x and y is different from the original function we had. Because of this, we must always check our results when finding the roots.

Answer 2

remember that when we are looking for the zeros of a function..we want to know where that function is eqaul to zero...ok
