<h3>What are algebra properties?</h3>Algebra properties are mathematical properties used to simplify algebraic expressions
In step 6, we have the following expression:
The additive property of algebra states that:
i.e. when a number or an expression is added to its inverse, the result is 0.
In , we have:
2 and -2
2 and -2 are inverses or opposites.
So, when they are added; the result is 0
Hence, the property used in step 6 is the additive inverse.

Answer:
Step-by-step explanation:
we know that
The quadratic function of the figure has a vertex at (2,-5) and the y-intercept is the point (0,3)
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
a is a coefficient
we have
substitute
with the y-intercept find out the value of a
For x=0,y=3
The equation is
Looking at the graph, the solution is the shaded area below the quadratic equation
so
the value of y must be less than or equal to the quadratic function
