Qụestion 1 : 6.65 ptsSkip to qụestion text.
If −x2+x+1≤f(x)≤−x+2 for all x, find limx→1f(x).
Enter only the valụe of the limit in the space provided below. If the answer is not an integer, enter it as a fraction in simplest form. Do not
enter a mixed nụmber. If the limit does not exist, enter “does not exist”.
Yoụr Answer: 1
Correct Answer(s):
1
Since −x2+x+1≤ f(x)≤ −x+2, by the Sqụeeze Theorem, limx→1−x2+x+1≤ limx→1f(x)≤ limx→1−x+2 −12+1+1≤ limx→1f(x)≤ −1+2
1≤ limx→1f(x)≤ 1Thụs, limx→1f(x)=1.
