f(x)=x³
reflected in the x-axis
Multiply whole right side by -1:

y = -x³
vertically stretched by a factor of 2,
Multiply right side by 2

y = -2x³
translated 5 units to the left
Replace x by (x+5)

y = -2(x+5)³
and 3 units down.
Add -3 to the right side:

y = -2(x+5)³-3   <--answer

The minus sign on the lead coefficient reflects the graph in the x-axis.

The lead coefficient of 2 stretches the graph vertically by a factor of 2.

The +5 inside the parentheses translates the graph 5 units left.

The -3 constant translates the graph 3 units down.
