#1 Tell Whether The Quadratic Has A Maximum Value Or A Minimum Value. The Find The Value. Round To The Nearest Tenth.

F(x)= -x² -6x - 7


#2 Let y = | x+a | +b, Where a ‡ 0 and b ‡ 0 . Explain how the values of a and b affect the graph of the functions as compared to the graph of y= |x|.



I NEED HELP FAST HURRY! THANK YOU!

F has a max. i'm not sure how to do it without calculus though. i guess there's something about the coefficients of F....


#2 Let y = | x+a | +b, Where a ‡ 0 and b ‡ 0 . Explain how the values of a and b affect the graph of the functions as compared to the graph of y= |x|.
the a moves the graph along the x-axis, the b loves it up & down. how? how about you figure it out... :wink:

You can complete the square to find the max.
