Question

The following limit represents the derivative of some function f at some point (a, f(a)). Select an appropriate f(t) and a

lim(t->1) (t^2 +t -2)/(t-1)

Answer 1

compare it wid the definition :

derivative = \(\large \lim \limits_{t \to a}~\dfrac{f(t) - f(a)}{t-a}\)

Answer 2

can u find some \(a\) and \(f(t)\) that match the given limit ?

Answer 3

a=-1?

Answer 4

f(t)=t^2?
