49. Sketch the graph cf an increasing Jncticn f such that hath f' (as) and A (m) = [ f) {it are decreasing. 12:51 PM Thu 15 Jun @ 75%O 0 -0 Also we want Aczy decreasing = ) A ( x ) = flac ) co - And Also we want fix ) decreasing = ) f" ( 2 ( ) 20 - 3 so we want these three conditions 50 I keep e Instead of ex and also I keep negative sign i e . fed) = - e co SO in the fix ) one negative sign comes out from differention of ( - x ) and one negutive sign asready there - ) flac ) = 02 Now due to negutive power of exponential Again while doing fix ) , negative comes out may be there are many other functions f which satisfy given conditions , But this is my one of the idea
