amorfide Group TitleBest ResponseYou've already chosen the best response.1
you have a function of x F(X)=3x²+x−2 to differentiate you multiply the coefficient of the unknown by the power of the unknown and decrease the power of the unknown by 1 for example f(x)=x² f'(x)=2(1)x^21=2x so f(x)=x f'(x)=1(1)x^11=x^0=1 if you have f(x)=2x² f'(x)=2(2)x^21=4x does this help? dw:1349804820461:dw

\[f(x)=3x^2+x2\] \[f(x+h)=3(x+h)^2+(x+h)2=3(x^2+2xh+h^2)+x+h2\] \[=3x^2+6xh+3h^2+x+h2\] \[f(x+h)f(x)=3x^2+6xh+3h^2+x+h2(32x^2+x2)\] \[=6xh+h+3h^2\]

divide by \(h\) and get \[\frac{f(x+h)f(x)}{h}=6x+1+3h\] take the limit as \(h\to 0\) get \(6x+1\)

you needed it done by hand right? not power rule it is a bunch of algebra, that is all only last step is calc, and that is taking the limit by replacing \(h\) by \(0\)

indeed @satellite73 has illustrated the given problem nicely with the formula i have given you ...i think that clears evrything
