I shifted this qn to the uni section, apparently its too challenging for pre-uni lvl. . Hope you guys can enlighten me.
The function g is defined by , x not equal to -3 and 5.
i) Find the coordinates of the turning point of the curve y=g(x).
ii) Hence, sketch the graph of y=g(x) and write down the range of the function g.
PS: Using calculus, I found the turning point to be (1, 1/-16).
