Find the missing factor D that makes the equality true -15y^4=(D)(3y^2)

Step-by-step explanation:

We have the equation:

And we want to find D such that the equation is true.

So, we can divide both sides by 3y². This will yield:

We can split this into:

Simplify. Hence:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
