Question

Identify the excluded value y= 4/x-5Correct expression: y = 4/(x-5)

Answer 1

Step-by-step explanation

We must find the value of x to be excluded from the function:

`y=(4)/(x-5).`

To have this function well defined, we must exclude the values that make zero the denominator. We see that the denominator is zero when x = 5. So we must exclude the value x = 5.

Answer

x = 5
