Answer:
B
Step-by-step explanation:
First, expand the function with FOIL
(3x - 4)(-6x + 5)
(-18x² + 15x + 24x - 20)
Combine like terms
(-18x² + 39x -20)
This is a quadratic function because it has x² and linear functions just have x.
So, B is the answer because it is quadratic and it has the correct quadratic, linear, and constant terms.
