The graph of a quadratic function with vertex (-2,0) is shown in the figure below. Find the domain and the range.

The domain for any quadratic is (-infinity, infinity).

The range is from the bottom to the top.  The graph bottoms out with a y-value of 0 at (-2,0).  It goes up forever.  The range is [0, infinty).

Be sure to use ( and ) on infinity.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
