I need some serious help please :(..
Make a summary table with these headings shown for each graph: Interval, Sign of Function, Sign of Slope, Change in Slope
I dont know how to figure out these??

Best ResponseYou've already chosen the best response.0at the back of the book, the intervals are x<1 and x>1

Best ResponseYou've already chosen the best response.0i understand the intervals, but not the rest of them like sign of slope..

Best ResponseYou've already chosen the best response.1sign of functions f(x)= infinity, if x=1 f(x)=1 to infinity, if interval is from 0<x<1 f(x)=infinity to 1, if interval is from1<x<2 f(x)=1 to approach zero, if interval is from x>2 f(x)=1 to approach zero, if interval is from x<2

Best ResponseYou've already chosen the best response.1sign of slope and change of slope y2 y1 slope m= x2  x1 from interval [2,1], f(2)=0.2 , f(1)=0.25 therefore 0.250.2 0.05 0.05 m1=== = 0.05 positive slope here 1(2) 1+2 1 from interval [1,0], f(1)=0.25 f(0)=1 0.251 0.75 m2=== +0.375 still positive here 11 2 the slope here is increasing from positive 0.05 to 0.375

Best ResponseYou've already chosen the best response.1look at the graph x=1, y=f(1)=0.25 x=2, y=f(2)=0.2

Best ResponseYou've already chosen the best response.1those are only approximation and assumption only to be able to know if you are on positive or negative slope changing decreasing or increasing

Best ResponseYou've already chosen the best response.1but if the sign is change from positive to negative it is decreasing function and from negative to positive sign it is increasing functon

Best ResponseYou've already chosen the best response.0ohhh it makes sense!! and then you do the same thing to the other side right, because what you did was x<1 (for slope) and then I do x>1 ?

Best ResponseYou've already chosen the best response.1next try that from interval [2,1] or from x=2 and x=1 find f(2)=? , and f(1)=? then find out if it is increasing or dec

Best ResponseYou've already chosen the best response.0okay so f(2)=1 and f(3)=0.25 Slope= 0.25  1 / (32) = 0.75 f(3)= 0.25 f(4)= 0.02 slope= 0.020.25 / (43) =0.23 Negative and decreasing!!! :D
