5(-2)(4)^2 + 2(4) + 7(-2)
5(-2)(16) + 2(4) + 7(-2)
-160 + 2(4) + 7(-2)
-160 + 8 + 7(-2)
-160 + 8 + -14
-160 + 8 - 14
-166
The answer is: -166.
Since percent means 'over 100', you can put 42 over 100:

. Since .42 is less than .44, that means that
.44 is your answer.
The equation of a parabola in vertex form, is:

Where <em>(h,k)</em> are the coordinates of the vertex.
From the given graph, notice that the coordinates of the vertex are:

The roots are the values of <em>x</em> where the graph crosses the x-axis. In this case, the graph crosses the x-axis at the points <em>(4,0)</em> and <em>(6,0).</em> Then, the roots are:

Substitute the values of the vertex into the equation of the parabola in vertex form:

To find the value of <em>a</em>, substitute <em>(x,y)=(4,0)</em>:

Therefore, the equation of the parabola is:
