Explain why the answer is h = 4!

26) Let  f(x)=x4−1x2−1  for  x≠−1,1 .

a. Sketch the graph of  f .

b. Is it possible to find values  k1  and  k2  such that  f(−1)=k  and  f(1)=k2 , and that makes  f(x)  continuous for all real numbers? Briefly explain.

27) Sketch the graph of the function  y=f(x)  with properties i. through vii.

i. The domain of  f  is ( −∞,+∞ ).

ii.  f  has an infinite discontinuity at  x=−6 .

iii.  f(−6)=3  

iv.  limx→−3−f(x)=limx→−3+f(x)=2  

v.  f(−3)=3  

vi.  f  is left continuous but not right continuous at  x=3 .

vii.  limx→−∞f(x)=−∞  and  limx→+∞f(x)=+∞

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
