graph{-(1/3)x^2 [-27.59, 27.98, -15.53, 12.27]}
for tracing any graph you should scrounge some points.
Explanation:
1) put some simple values of x and obtain y like, here, at x=0, y=0
at x=
at x
2) check for maxima and minima of function using derivative.
3) also put some simple points like at x=
4) interchange x and y, if no change appears it means the
With little practice I hope you will be able to trace curves.
