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

true
false

False, this would imply that

but we have

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

47 - 90 = 43

43 - 180 = x

x = 137

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
