Question

Use the expression es002-1.jpg.
How many excluded value(s) are there?

Answer 1

I can’t see the image file. Could you either paste the expression here or type it out (for example " (x+1)/(x^2-4) ")?

In the meantime, here’s how to find excluded value(s):
- For rational expressions: set every denominator factor = 0 and solve; those solutions are excluded (even if a factor cancels).
- For even roots (square root, 4th root, etc.): set the radicand ≥ 0 (so values that would make it negative are excluded).
- For logarithms: require the argument > 0.
- For combinations, apply all applicable restrictions.

If you paste the expression I’ll find the excluded value(s) right away.
