Question

The point (4, -2) lies on the graph of f(x) = sqrt of x

True
False

Answer 1

The answer is false, hope that helps

Answer 2

False, this would imply that

`√(4)=-2`

but we have

`√(4)=2`

In general, the range of the square root function is the set of positive integers, so you can never have a negative y coordinate on the graph of
`y=√(x)`
