Question

Y=1/x-5 + 2
For what value of x is the value of y undefined

Answer 1

The value of y is undefined for values of x that make the denominator of the fraction equal to zero, since division by zero is undefined in mathematics. In this case, the denominator is x - 5, so the value of y is undefined when x - 5 = 0. Solving for x, we get:

x - 5 = 0

x = 5

Therefore, the value of y is undefined when x = 5, since it would make the denominator equal to zero.
