Question 115322: can someone help me solve this problem?
1. consider the function f(x)=x^2 + 6x - 2
A. find h, the x-coordinate of the vertex of this parabola.
answer_______________________________________________
B. Substitute the two whole number values immediately to the left and right of h into the function to find the cooresponding y. Fill in the table below. Make sure your x-values are in increasing order in your table.
x y
__h=___ ________
_____ ________
_____ ________
_____ ________
_____ ________
C. Use microsoft exel to graph the function by plotting the points found in the table in part B.

Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
A) the vertex lies on the axis of symmetry ___ the equation is x=-b/2a ___ x=-6/(2*1) ___ x=-3 ___ this is the h value
B) the two numbers to the left (less than) of h are -5 and -4
___ the two to the right (greater than) are -2 and -1
___ plug the numbers as x-values into f(x) and find the corresponding y-values ___ y IS f(x); same thing, different name
___ enter the values in the table
C) good luck with excel
