The point (2, 8) is on the curve y = x 3 px + q. a.
Question:
The point (2, −8) is on the curve y = x3 − px + q.
a. Use this information to find a relationship between p and q.
b. Find the gradient function dy/dx.
The tangent to this curve at the point (2, −8) is parallel to the x-axis.
c. Use this information to find the value of p.
d. Find the coordinates of the other point where the tangent is parallel to the x-axis.
e. State the coordinates of the point P where the curve crosses the y-axis.
f. Find the equation of the normal to the curve at the point P.
