Best ResponseYou've already chosen the best response.0well... the situation is the same as before really notice the leftsided limit, it ends up at 1 whilst the rightsided limit ends up at 4 so they don't meet, thus the doublesided limit does not exist

Best ResponseYou've already chosen the best response.0use the power rule keep in mind that derivative of a constant is 0 \(\bf \cfrac{d}{dx}[8x+4]\implies \cfrac{d}{dx}[8x]+\cfrac{d}{dx}[4]\)

Best ResponseYou've already chosen the best response.0well. the derivative of 4, a constant is 0 what about the derivative of 8x? using the power rule you'd get?

Best ResponseYou've already chosen the best response.0yeap, is a constant, is 8 so that's the derivative f'(x) = 8 now if we set x = 9 the derivative or the function, doesn't change, still 8, since it's a constant

Best ResponseYou've already chosen the best response.0The position of an object at time t is given by s(t) = 9  3t. Find the instantaneous velocity at t = 8 by finding the derivative. @jdoe0001

Best ResponseYou've already chosen the best response.0hmm not very sure on that one if we were to take the derivative, is just 3 a constant, thus t = 8 will make no difference on the derivative but you may want to repost, since I'm not sure on that one
