|dw:1339053693213:dw| Do u mean this?

2. FatimaISWA

yes

3. maheshmeghwal9

k! see that where at what critical points I mean x's values; denominator is zero. those values will be excluded since $y/0=\infty$ (undefined). Can u give me answer, what r those values?

4. maheshmeghwal9

gt it?

5. FatimaISWA

yes i did!

6. maheshmeghwal9

k! np:)\ x={5,-5} will be excluded:)

you must exclude 5 and -5 because the denominator must not always equal to zero (0)
