how do i find the slope of a tangent line at given point (c,f(c)) of f(x)=x^4+3x^3-x^2+4; c=1?

OpenStudy (alekos):

do you know how to differentiate?

OpenStudy (anonymous):

like 4x^3+9x^2-2x?

OpenStudy (alekos):

that's it. so now you just substitute x=1 into this equation and you'll have the slope of the tangent!
