Question 667924: on the graph it shows the equation y^4=x
(a)at how many points does x=4
(b) at how many points does x=-4
You do not have to find the value of these points,just tell how many there are

on the graph it shows the equation y^4=x
Comment: Notice that x is a number raised to an even power;
so x is never negative.
--------------------------
(a)at how many points does x=4
If x = 4, y = 4^(1/4) which can be both positive and negative.
ANS: 2
-------------------
(b) at how many points does x=-4
x Cannot be negative
Ans: 0
