Answer:
y>0
Step-by-step explanation:
This is because no matter what x-value you enter, the fact that it's an even exponent will make the y-value always positive. And regardless of the 4 in the exponent, you can still have values less than 4 (but still positive).
X = 100
X + 20 over 4 = 30
1/4x + 5 = 30
-5 -5
1/4x = 25
multiply both sides by 4
x = 100
m= -5/6
4.58
Sq rt of 21 3x7= 21
