<u>Equation of a Polynomial</u>
Given the roots x1, x2, and x3 of a cubic polynomial, the equation can be written as:
Where a is the leading coefficient.
We know the three roots of the polynomial -6, -3, and 1, thus:
Since the y-intercept of the polynomial is y=90 when x=0:
90=a(0+6)(0+3)(0-1)
90=a(6)(3)(-1)=-18a
Thus
a = 90/(-18) = -5
The polynomial is:
We must write it in standard form, so we have to multiply all of the factors as follows:
2(4+2x)≥5x+5
4+2x≥5/2x+5/2 (divide both sides by 2)
3/2+2x≥5/2x (subtract 5/2 from both sides)
3/2≥1/2x (subtract 2x from both sides)
3≥x (multiply both sides by 2)
or x≤3
Hope this helps
Y=4/3 because if 3 goes to rhs is becomes divided by the number on the rhs so answer is 4/3
Based on the given points, the point that is located on the y-axis is (0,7).
<h3>Which point is on the y axis?</h3>
The point that is on the y-axis should have a coordinate such that x is equal to 0.
This leads to the point being on the y-axis because the nonzero coordinate of the y axis would then have to be placed on the same axis.
The only point with a 0 coordinate is (0, 7) so this is the point that is located on the y-axis.

Answer:
Okay look at the graph, at x = 11, the y of the line is between 500 and 450. 500+450=950
950/2=475 so (11,475)
Let's take x=6, the y would then be 600. If x=9, y would be 525. Just try to look at the graph and see from there. Let me know the answer.
