Question

here is a sketch of y=x^2 + bx + c. the curve intersects the x-axis at (2,0) and the point P the y-axis at (0,-14). work out the x- coordinate of the turning point

Answer 1

Answer:

y=a x^3+b x^2+c x+5` touches the x-axis at `P(-2,0)` and cuts the y-axis at the point `Q` where its gradient is 3. Find the equation of the curve completel
