The answer is 104.4 because 38+65 is 103. then you add the decimal part of the equation which is 37. If you are rounding to the nearest tenth it would be 104.4
38.94 rounds up to 40 as it is more than half-way between 30 & 40. 65.43 rounds up to 70. even though 65 is half-way, .43 makes it closer to 70 than 60.
The answer is C. The domain is all points between -8 and 8 since it keeps waving back and forth. The range is all real numbers the graph continues on forever. And it is not a function because it does not pass the vertical line test
