-3x>6 What is the solution set?
1 answer:
Here we have the following inequality:
So divide both sides by -3:
When multiplying or dividing an inequality by a negative number, the direction of the inequality changes. That's the reason why we changed the sign from > to <. Finally, the solution set is:

Answer:
Step-by-step explanation:
Hello,
<em>"Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only."</em>
We know that Kelsey is right, a polynomial of degree 3 has maximum 3 zeroes, so it means that the graph of this polynomial has maximum 3 x-intercepts.
<u>So how Ray can be right too?</u>
we need to think of y-intercept, if we add the y-intercept then Ray can be right too,
as you can see in one example below
there are 3 x-intercepts and 1 y-intercept.
This being said, Ray is not always right. For instance
has only 1 zero (multiplicity 3) its graph has only 1 intercept in the point (0,0)
hope this helps
