Answer:
Edward is correct
Step-by-step explanation:
When denominator =0 , then the function becomes undefined
Now we look at the values of x that makes the denominator 0
We set the denominator =0 and solve for x
(x+1)(x-2)(x-4) =0
x+1=0 so x= -1
x-2=0 so x=2
x-4 =0 so x=4
x=-1 , 2 and 4 makes the denominator 0. that is undefined
So Edward is correct
The discriminant is
which is 0.
Since the discriminant is 0, there is only one real solution.
