Question 98

The population NNN (in thousands) of a specific bacterial culture is modeled by the function

N(t)=14(t3−7)4,t≥2 N(t) = \frac{1}{4}(t^3 - 7)^4, \quad t \ge 2 N(t)=41​(t3−7)4,t≥2

where ttt is the time in hours since the start of the observation.

Determine the equation of the tangent to the curve N(t)N(t)N(t) at the point where t=2t = 2t=2.
