Question

Find the derivative of the function y = 2x^2 - 13x + 5 and use it to find the equation of the line tangeant to the curve at x = 3

Answer 1

y'=4x - 13
and at x = 3
y'(3) = -1

Answer 2

Can you show me how you did it?

Answer 3

the derivative?

Answer 4

Yea

Answer 5

y'=n x^(n-1) right? and the derivative of any constant is 0 so the 5 at the end of the equation equals 0

so,

y = 2*2 x^(2-1) - 13 x^(1-1) +0
= 4x - 13

Answer 6

OHHHHHHHHHHH You just jump started my memory from last year's math class, thanks.

Answer 7

haha np man

Answer 8

do you reckon you can help with my question?

Answer 9

Uhhh I might what is it?
