Answer:

Step-by-step explanation:
We have been given the function

From the rational zeros theorem, we have

From the given function,
Leading coefficient = 2
Factors of 2 are 1,2
Constant term = 18
Factors of constant term = 1, 2, 3, 6, 9, 18
Hence, we have

Answer:
Range is between -7 and 8
-7<y<8
Step-by-step explanation:
Range means series of number between lowest and highest output(y-axis) of a function.
Notice on the graph, the lowest y you can get is -7 and highest is 8. Other numbers are in between.
Thus, the range is in between of -7 and 8.
Answer:
-7
Step-by-step explanation:
-7 is the number that is attached to the y. It is the coefficient. Another possible coefficient is 1, but you do not need to write it, as anything multiplied by 1 is equal to the original number.
