>>1st one- at X=0 Y=DNE so the function is not continious.
>>2nd one- there is Y value for every X so the function is continious.
>>3rd one- there is Y value for every X so the function is continious.
>>4th one- f(-1)=1 does not equal the limit of f(x).
because the limit as X aprroaches from the left and from ther right is different.
a - b ≤ 25
b - yes
c - 26 ( draw the picture for your explanation)
2(3.14)r = Circumference
r = d/2
r = 43
2 x 3.14 x 43 = 270.04 cm
The answer is A.
Add all the number values together and then divide it by the number of values you have: 43+32+65+88+50+72=350
350/6=58.33
