Let (c) 11] The function is defined by f:x-0.5x²+2x+2.5. (a) Write down (1) (b) f'(x); (ii) ƒ'(0). Let N be the normal to the curve at the point where the graph intercepts the y-axis. Show that the equation of N may be written as y=-0.5x+2.5. g:x-0.5x+2.5 (1) (ii) Find the solutions of f(x) = g(x) Hence find the coordinates of the other point of intersection of the normal and the curve.
