Question

help please the lim->t(t^4+t-2)/(t-1) reprsents the derivative of some fucnction f at some number a , find f and a with steps please

Answer 1

In general, the derivative of a function f at some point a can be calculated as: limit of [f(t) - f(a)]/[t - a] when t tends to a.
If you use this in your formulation you get: f(t) = t^4+t-1 and a = 1
