Sorry i gtg
Give me a couple more minutes and i will find it for you :]
My parents can't make up there minds i have to go i am so sorry... :[
it's fine! Byee! And thanks again
y=-(x+2)(x-5) is a downward facing parabola with x-intercepts (-2) and (5)
http://www.algebra.com/algebra/homework/complex/Complex_Numbers.faq.question.164513.html will this help?
Thanks:) So what would be the range?
to find range, first find the axis of symmetry, which is the x value exactly between -2 and 5
would that be 1,9
not quite what number is exactly halfway between -2 and 5?
1 and 2
nope, 3 is closer to 5 than -2
what number is exactly in the middle of 1 and 2?
not quite, try one more time
right, so our axis of symmetry is x = 1.5 now, to find our range, find f(x) when x = 1.5
by pluggin in?
multiply all that out and we get...?
so our range is (-infinity,12.25]
our axis of symmetry is x = 1.5
yayy! Thanks so much:)
and our vertex is (1.5,12.25)
