Respuesta :

It’s undefined at x=-1 because the denominator would be 0

Answer:

x = - 1

Step-by-step explanation:

Given

f(x) = [tex]\frac{2x-3}{x+1}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.

Solve x + 1 = 0 ⇒ x = - 1 ← excluded value
