Answer:
D
Step-by-step explanation:
First you need to make it either -tan(x) or tan(-x) to get it oriented correctly (Flipped over the x or y axis, either works) and then moved left or right by pi/2, again, either works. You cannot have both tangent itself and x be negative though, like in C, because that just undoes the flipping. just like a +pi/2 would undo a-pi/2.
A simple rule to tell whether a graph is a function is to pretend to cut it vertically, if any cut intercept the graph twice, it is not a function. otherwise, it is.
In this case, the heart is not a function, because if you cut it up-down direction, your imaginary knife will touch the edge of the heart twice.

Answer:
5xy^2(y + 3x^2 - 6x).
Step-by-step explanation:
5xy^3 + 15x^3y^2 − 30x^2y^2
The GCF is 5xy^2 so dividing through by this we get the factors:
= 5xy^2(y + 3x^2 - 6x).
