This is from our problem set.
f(x)= 2(x^3)3(x^2)12x+20
write an equation of the line perpendicular to the graph of f at x=0
I think i'm supposed to take the derivate of f and then find the slope of the tangent line at x=0. Then take the opposite reciporcal of that and put this slope and the point (0,20) into pointslope from to get the equation but i'm not exactly sure if this is write. So, can someone help me.
Thank YOu
