Question

Suppose you need to solve a system of two equations in which one equation is y=(x+2)(x-3)(x-6) and the other equation represents a horizontal line. How many solutions could your system have?

Answer 1

1

Answer 2

that's a cubic equation, which is always increasing, so this cubic function would cross the horizontal line only once

Answer 3

Only one is not an answer I have

a) 1,2,or 3 solutions
b) 0,1, or 2 solutions
c) 2,3, or infinitely
d)1 or 2 solutions
e) 2 or 3 solutions
