I can’t see the image — could you paste the rational expression (or re-upload the image)?
How to find excluded values:
- Set the denominator = 0 and solve. Any root of the denominator is an excluded value.
- If a factor cancels (same factor in numerator and denominator), that value is still excluded (a removable discontinuity).
Example: if the expression is (x^2 + x − 6)/(x^2 − x − 6), factor: numerator = (x+3)(x−2), denominator = (x+2)(x−3). Denominator zeros: x = −2 and x = 3, so the excluded values are −2 and 3.
Send the expression and I’ll give the exact excluded value(s) from your options.
