Let f(x)=4/x
a. use the definition of the derivative to calculate the derivative of f .
b. find the slope of the tangent line to the graph of f at point (-2,-2)
c. write an equation of the tangent line in part b .

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

step-by-step explanation: yes

25/6 hope it : )
