Answer:
A function means that we get one input and one output. In this example that means for every x-value that we have, we only have one y-value.
Looking at the first option, we can see that there is no x-value that has more than one y-value which means that it is a function.
The rest of the options are seen with at least two values for one x-value in one of the points. Therefore, they wouldn't be considered a function leaving us with only option A as the solution.
Answer: 23
If x=-1 then (-1) to the power of 3 = -1 and (-1) to the power of 2= 1
3(-1)^3= -3
2(-1)^2= 2
-3+2+25= 23
That is equal to 70 - 8 x 6
