how to approach this problem

If F(x) -64/x^2 and it wants me to find an equation that decribes its position at (8,-1)

which way do you think is best to find this out using the division of deritives or get it by limts

just put the value inside the funtion!! You should only use limits when the function foes not exist at the point you are looking for, as this isn't the case, you should just use the value
