Answer:
Not on a coordinate plane
Step-by-step explanation:
We must use absolute value because lengths should always be positive you cannot have a negative length or distance.
The illegal values of b are when the denominator equals 0.
So, gives you (b-4)(b+2)=0
Therefore, b=4 and b=-2, which is answer A.
3√-64 = -4
The answer is -4.
