How do you find the inflection points for the function #f(x)=8x+3-2 sinx#? Calculus Graphing with the Second Derivative Determining Points of Inflection for a Function 1 Answer Jim H Apr 24, 2015 #f(x)=8x+3-2 sinx# #f'(x)=8-2 cosx# #f''(x)= 2 sinx# #f''(x) =2sinx = 0# at every integer multiple of #pi# and, we know the sine changes sign at every #x# intercept, so every point: #(n pi,0)# with integer #n# is an inflection point.
