for b) the question literally means swayp x and y values, like

x^3+y^3=1 --> y^3+x^3=1 this proves them to be diagonally symmetrical

for c) its just implicit deifferentiation which results out to be = -x^2/y^2 and simply find the TP and POI

for d) its simple take limits to pos and neg infinity

If you need worked out example, im happiliy willing to do them, just ping me if you dont understand a question specifically
