Question 8

+6 marksNumerical answer

The profit of Company A with respect to time (in months) is given by the function f(t)f(t) (in lakhs) as follows:

f(t)={(t−3)n+1−1t−4if 0≤t<4,⌊t+1⌋+tif t≥4f(t) = \begin{cases} \frac{(t-3)^{n+1}-1}{t-4} & \text{if } 0 \leq t < 4, \\ \lfloor t+1 \rfloor + t & \text{if } t \geq 4 \end{cases}

for some integer n>0n > 0.

The profit of Company B with respect to time (in months) is given by the function g(t)g(t) (in lakhs) as follows:

g(t)={t2if 0≤t<2,2tmif t≥2g(t) = \begin{cases} t^2 & \text{if } 0 \leq t < 2, \\ 2t^m & \text{if } t \geq 2 \end{cases}

for some integer m>0m > 0.
