Answer:
First, you would need to find a common denominator for the two, in this case it would be 6 which would make the equation 3/6 + 4/6=7/6. Then in order to make the answer a mixed number you would need to divide the numerator into the demonanator, write down the whole number answer (6 will go into 7 ONE time) then write down the "leftovers". The final answer would be 1 1/6
(i hope this helps! im not the best at explaining)
To know if it is function, we need to check if each input value only leads to one output value.
In this graph, input values are led to just one output value, so the correct answer is [ Yes, because each x-value has exactly on corresponding y-value ]
We can also check the vertical line test. The line doesn't pass through more then once which proves out answer.
Best of Luck!
The answer to this is (x+16)x(x-1)
