I find it best to switch everything exponents when taking derivatives.
F(x) = 7/x
Same as..
F(x) = 7x^-1
Take derivative..
F'(x) = -7x^-2
Plug in x = 1
F'(1) = -7(1)^-2
F'(1) = -7
To find the area of a square it is 10x10=100 units and to find perimeter it is 10x4=40 units so the area is larger
It would be C
hope it helped
The answer is A. (-2,-3)
You can use your graphing calculator and go to Matrix and edit. Then plug in the values and next, go to rref and find the values.
