c. f(x)=x'+x2 -x-1 [0,2], k =0.1 anoted. f(x)= *-3 5,9], k = 0.05 Avg rate Instantaneous rate Avg rate Instantaneous rate e. f(x)= [1,2],k =0.01 f . f ( x ) = 2" + 2-* [0,2], k= 0.01 Avg rate Instantaneous rate Avg rate Instantaneous rate 3. Using k = 0.1, determine at which value of x the given function changes faster. Check the graph to confirm. a. f (x) = 2x* + x -4, x = 0 and x =1 Compare b. f(x) =-x'+6x2+4x-1, x=-2 and x= 2 c. Jer is deep sea diving and is at depth 200 feet. He must ascend very slowly or will suffer the bends. His depth D is given by D(t) =-200 + 1.I' where t is measured in minutes and negative values of D means he is below sea level. Determine if he is rising faster at a half hour or 3/4 of an hour into his ascent
