Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have stumbled upon this maths problem, i have pondered it for a few days without any real work until today. The problem is, i can't seem to comprehend these questions at all... so any help would very much appreciated

Here is the math problem:

The curve C has equation y=k*x^3-x^2+x-5, where k is constant.

A) Find the derivative of the expression with respect to x

I got 3*k*x^2-2 x+1=y

The point A with x-coordinate -1/2 lies on c. The tangent c at a is parallel to the line with equation 2*y-7*x+1=0

Find:

B) the value of k

C) the value of the y-coordinate of A.
