SOLUTION: Hi all, I'm trying to get my head around a graphing question. It's a function f:x where {{{4 - x - x^2}}} The domain is {{{-3 <= x <= 2}}} and {{{x = R}}} Thanks in advance,

Question 972826: Hi all, I'm trying to get my head around a graphing question. It's a function f:x where 4+-+x+-+x%5E2
The domain is -3+%3C=+x+%3C=+2 and x+=+R
Thanks in advance, I'm scratching my head!!

You can put this solution on YOUR website!
Write it like this:
+f%28x%29+=+-x%5E2+-+x+%2B+4+
The y-intercept is ( 0,4 )
Other points are:
( 1, 2 )
( -1, 4 )
Here's the plot:
+graph%28+400%2C+400%2C+-6%2C+6%2C+-6%2C+6%2C+-x%5E2+-+x+%2B+4+%29+
------------------
The domain is between the points
( -3, -2 ) and
( 2, -2 )
