They are identical lines so they have infinity pairs
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
The answer is x = 0, -13/2
Answer:
4/5 - 1/4
Step-by-step explanation:
