Question

f(x)=x^5-2x+1......find the equation of the tangent line at x=1

Answer 1

Is it 0?

Answer 2

take the derivative, evaluate at 1 to find the slope, then use the point slope formula

Answer 3

\[f(1)=0\]
\[f'(x)=5x^4-2\]
\[f'(1)=3\] use
\[y-y_1=m(x-x_1)\] with
\[x_1=1,y_1=0, m=3\]

Answer 4

So i basically only did half of the equation?

Answer 5

yeaaa but you still did a good job

Answer 6

lol thnks, but i still feel like a fail...i wnt to finish the WHOLE equation. ;(
