If y=f(x) is a polynomial function and graph of y=f′(x) in interval

1.	If y=f(x) is a polynomial function and graph of y=f′(x) in interval (1,8) is shown in figure below, then consider the following data in interval (1,8) If a = number of point(s) where y=f(x) has maxima b = number of point(s) where y=f(x) has minimalongest interval of y=f(x) is decreasing is (m,n) then value of (m+n+a+b) is
Answer» If $y = f (x)$ is a polynomial function and graph of $y = f^{'} (x)$ in interval $(1, 8)$ is shown in figure below, then consider the following data in interval $(1, 8)$ If $a$ = number of point(s) where $y = f (x)$ has maxima $b$ = number of point(s) where $y = f (x)$ has minima longest interval of $y = f (x)$ is decreasing is $(m, n)$ then value of $(m + n + a + b)$ is
