Question 116137: Please help with the numbers for part 2 left and right of H? Please show the work in finding the numbers?
Thank You. Consider the function .?
Consider the function .?
f(x)=x^2-8x+12
a) Find h, the x-coordinate of the vertex of this parabola.
b) Substitute the two whole number values immediately to the left and right of h into the function to find the corresponding y. Fill in the table below. Make sure your x-values are in increasing order in your table.
x y

You can put this solution on YOUR website! f(x)=x^2-8x+12
a) Find h, the x-coordinate of the vertex of this parabola.
x = -b/2a = -(-8)/(2*1) = 4
---------------------------------
b) Substitute the two whole number values immediately to the left and right of h into the function to find the corresponding y. Fill in the table below. Make sure your x-values are in increasing order in your table.
x y
If x = 2, y = 4-16+12 = 0
If x = 3, y = 9-24+12 = -3
If x = 5, y = 25-40+12 = -3
If x = 6, y = 36-48+12 = 0
==============================
Cheers,
Stan H.
