Question

please help me!?
Identify the excluded value for the rational function.
y= 4/(x-1)

A. 2
B. 3
C. 0
D. 1

Answer 1

solve \(x-1=0\) in one step
add one to both sides

Answer 2

x= 1?

Answer 3

That would be correct "excluded values" occur when the denominator = 0....so x - 1 = 0

when you add 1 to both sides you have x = 1

so yes ...good work! :)

Answer 4

thank you so much!! :)

Answer 5

yes \(x=1\)
