Answer :

Since the denominator is zero, which means that direct substitution cannot be used to find the limit and the limit is undefined.

The given function is:

[tex]\lim_{x \to 1}[/tex] (x – 8x +9)/ (2x-2)

To do this, substitute the value of x directly into the expression and evaluate it.

Plugging in x = 1, we have:

(1 – 8(1) + 9) / (2(1) - 2)

Simplifying the numerator and denominator, we get:

(1 – 8 + 9) / (2 - 2)

Combining like terms, we have:

(2) / (0)

Since, the denominator is zero, which means that direct substitution cannot be used to find the limit.
