Each of the following functions f is continuous on the given set d. determine whether f is uniformly continuous on d. justify your answer by providing a brief explanation (just a sentence or two, no formal proofs).
#7(a) f(x)= 4^x/x^4 d = [1/9, 9]
#7(b) f(x)= 4^x/x^4 d = (0, 9]
#7 (c) f(x)= (x^2 + 5x) /2x + 10 d = (−5 , 5)
#7 (d) f(x)= x sin(3/x^3 ) d = (0, 1)

the answer is c

hope this !

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
