Best ResponseYou've already chosen the best response.1@Akshay_Budhkar , we can find that by simply using area of a square? right?

Best ResponseYou've already chosen the best response.3are you clear with A ?

Best ResponseYou've already chosen the best response.1@Akshay_Budhkar idk but i feel like we have to find some derivatives?

Best ResponseYou've already chosen the best response.3ok now let degrees be d and time be t so on y axis we have d/t and x axis we have t Now till x= 1 it is a straight line, with a slope 8 and intercept 8 so the equation is y=mx+c that is y=8x8 that is d/t=8t8 d=8t^2=8t

Best ResponseYou've already chosen the best response.3Now for minima or maxima the first derivative of the function is o therefore\[{d(d) \over dt }=0=16t8 \therefore t= 1/2\]

Best ResponseYou've already chosen the best response.3Now to find if it is a minima or a maxima we take the second derivative. if it is negative it is a maxima if positive minima ( mostly i maybe mixing them ) so in this case it is 16 which is negative. therefore it is a maxima at 1/2

Best ResponseYou've already chosen the best response.0Thank you so much I understood that! Would you be able to help me with question 4 by chance?

Best ResponseYou've already chosen the best response.3ok lemme see, is it one unit for each square right?

Best ResponseYou've already chosen the best response.0That is what I understand.

Best ResponseYou've already chosen the best response.3ok lets start with the simplest C. f(3) = 5 any doubt?

Akshay_Budhkar

Best ResponseYou've already chosen the best response.3ok now A. f'(2) Now i believe that at a given point \[f'(x)={dy \over dx} = { y \over x}\] if we estimate. so f'(2) =2/2 = 1

Best ResponseYou've already chosen the best response.0Okay, that makes sense to me.

Best ResponseYou've already chosen the best response.3for D its the same logic, area under the curve. i believe you can assume the graph to be a triangle and calculate the area

tburn

Best ResponseYou've already chosen the best response.0So you think D would be =2 to 4?

Akshay_Budhkar

Best ResponseYou've already chosen the best response.3the area under the graph , from 2 to 4

Akshay_Budhkar

Best ResponseYou've already chosen the best response.3Can you solve it? For the other questions i would personally plot a graph for f'(x)

Akshay_Budhkar

Best ResponseYou've already chosen the best response.3yes i know. Now to plot the graph u must know that it is zero at minima and maxima, and u can fidn approximate values by using the approximation of y/x, and plot the graph of f'

Akshay_Budhkar

Best ResponseYou've already chosen the best response.3then after i get the graph, f"' will be obtained by using y/x again and the last one by area under curve in that graph

Best ResponseYou've already chosen the best response.3yup give it a thought, and lemme know if ustuck =D and u can tag me in some other question if u get some similar doubt =D
