The polynomial is subtracted using the distributive property.
.. (16k^3 -3v^4) -(-9k^3 +6v^4)
.. = 16k^3 -3v^4 +9k^3 -6v^4
.. = (16 +9)k^3 +(-3 -6)v^4
.. = 25k^3 -9v^4
"Invert" means different things in different contexts. Here we suppose it means you simply want the reciprocal of this difference:
It is 500% because it is increased by 5 times.
The answer is: 
By definition, a point is a local minimum if it has the smallest <em>y</em> coordinate in that interval and the graph goes from decreasing to increasing.
Based on this information, you can graph the points given in the problem above, as you can see in the figure attached. Then, you can notice that the ordered pair that is closest to a local minimum of the function is the last option shown in the problem.

Answer:
The table with the y values of 1, 4, 16, 64, and 256 represent an exponential function.
This table shows an exponential function. This is easily seen by looking at the values of y. As you go down the rows of the y-values, you notice that the numbers are being multiplied by the value of 4.
1 x 4 = 16
16 x 4 = 64
64 x 4 = 256.
