So,is undefined for the following values. (Enter your answers as a comma-separated list. If an answer does not exist, enterDNE.)Part 3 of 3Since there are no real roots fory2−2y+8,g'(y) exists for all real numbers. This means critical numbers occur whereThis happens only when the numerator equals 0. Thus, the critical numbers are as follows. (Enter youranswers as a comma-separated list. If an answer does not exist, enter DNE.)
