maybe the professor didn't explain it well here is the thing i need to do a numerical analisys  of functions the asked me to use some methods (secant, flase position,newton ,etc) so i need a value out of the graphic ( i think it is the one i mentioned ) BUT it may be be the slope  i have that problem please help me on this because its killing me

my professor gave it to me he just gave some random functions and said " graphicate them then get the correlation  coefficient out of them " and no there is no table near as you said i need points but he never gave us any
