Be just a bit clearer, please: "find the vertex."
You could either "complete the square" or use the "quadratic formula."
Here the coefficients are a=-1, b=11 and c=-18. Because a is -, the curve opens downward and the vertex is on top, representing the function's maximum.
Use the quadratic formula with the coefficients given above.
-b plus or minus sqrt(b^2-4ac)
x = -------------------------------------------

<u>ANSWER: </u>
The vertex of given equation is (6, 32).
<u>SOLUTION:
</u>
Given, quadratic equation is
Above equation is a parabola and we need to find the vertex of that parabola. We know that, general form of the parabola is
Where, (h, k) is the vertex.
So, let us convert the given equation in parabolic equation.
Now, by comparing above equation with general form,
h = 6, k = 32 and a = -1.
Hence, the vertex of given equation is (6, 32).
Answer:
y is the vertical axis. x is the horizontal axis. Replace any value in x to get your y value. The value you input as x is your x value. God this sounds confusing. I'd graph it for you but i don't know how to do that on Brainly.
