Question 12 Determine the limit 1 point lim (# 1sin(82) + COS (82)1 if it exists. Enter 'NA' (without the quotation marks) if limit does not exist. Answer : Question 13 Determine the range of the function 1 point where r E [0, 1] Answer: The range of f is [a, b], where 1 = Number Number Question 14 Determine the range of the function f(z) = 1+22 -1 1 point where I E [0, 6] Answer : The range of the function f is [a, b], where a = Number b = Number Question 15 Determine the range of the function f(x) = sin(x) + 15sin(x)|. 1 point Answer : The range of f is [a, b] where 1 = Number b = Number
