Answer:
7
Step-by-step explanation:
f(-1)=-1*(-1)*2-3*(-1)+2 → f(-1)=2+3+2 → f(-1)=7
Answer:
J.
Step-by-step explanation:
There is no solution because these are parallel lines.
Parallel lines never intersect and so they have no solution.

Answer: Graph 10 and 12 are both functions while graph 13 is not a function
Step-by-step explanation: The best way to know if the graph is a function is by the vertical line test, if the points on the graph pass through the straight vertical line more than once, it is not a function, but if it passes though the line only once then it is a function. Now for the Domain and range, the best way to see it is as DomainX and RangeY, this is something I learned when I did functions, and it helped me a lot. Now if you look at 10 and 12, both go on infinitely, as they have no stopping point, meaning that the domain would be (-infinity, infinity), and for 13 you can simply put the coordinates for each point in a chart, with your X and Y, remember DomainX and RangeY, this should help you understand which is X and which is Y. I hope this helped a bit. Now for RangeY, for 10, look for the lowest number in the Y axis that the line goes, for this case its, -1, and then look for the highest number on the Y axis that the line goes, aka 3, now use this as a example and you can easily find 12's Range.
Answer
0
Explanation
Formula for sum of interior angles:
(n - 2) • 180 = sum = 2205 °
Where n = number of sides
2205/180 = n - 2
12.25 = n - 2
14.25 = n
Answer is 0 as you can’t have a quarter of a side
