The point (2,0) represents a relative minimum and an x-intercept.
<h3>How to determine the property?</h3>The missing graphed function is added as an attachment
The point (2,0) means that:
x = 2 and y = 0
On the attached graph, we can see that the graph touches the x-axis at (2,0); this represents the x-intercept
Also, the graph has a minimum at (2,0); this represents the relative minimum
Hence, the point (2,0) represents a relative minimum and an x-intercept.

Answer: Choice C) Multiplication property of inequality
The rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.
Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips
Example 2:
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip
Similar rules apply to a > b,
