lol

parthkohli · Answer

Let's write the equation like this:$$y+2 = 5(x-7)^3$$Or like$$y+2 = (5^{1/3} x - 5^{1/3}\cdot7)^3$$This may look confusing, but you may be starting to se the similarities with the original equation.

hold up let me draw it for you parth bby

parthkohli · Answer

You don't even need to draw it, really. 
It's just clear that both graphs are gonna be translated and stretched out in a weird manner.
