Step-by-step explanation:
First notice that f(x) is negative, so entire graph will be below x-axis.
Next find domain by setting what is inside sqrt greater than 0.
You can't take sqrt of neg number.
Finally plot some points, start at x = 1, y=0.
Then try x = 0, y = -1.
x = -3, y = -2.
Connect the points, done.

x-------> the length of <span>a rectangular cookie sheet
we know that
area of </span><span>a rectangular cookie sheet=length*width
area of </span>a rectangular cookie sheet=192 in²
area of a rectangular cookie sheet=<span>x² + 4x-----> x*(x+4)
</span><span>Step 1: x² + 4x = 192
</span><span>Step 2: x(x + 4 ) = 192 The length is x. The width is (x+4)
</span><span>Step 3: x² + 4x = 192=0
we have
</span>x² + 4x = 192
x² + 4x - 192=0
using a graph tool-----> to resolve the second order equation
see the aattached figure
the solution is
x=-16
x=12
(x+16)*(x-12)=0
the length is x=12 in
and the width is-----> (x+4)-----> 12+4----> 16 in
<span>Step 4: (x +16) (x - 12) = 0
Because the length can't be -16 the length is 12, and the width is 16</span>
