Only took me 45 minutes to type this up .... not setting any records here :P
Please try using Stapel sources before using my results. I am trying to practice using latex and it took me approx 45 minutes to type this up (yes I am slow) and I do not want to lose my work; therefore, I am going to post it, but you should try to do the work yourself first.
Vertex = ( )
x-int = -1 and
y-int = 5
domain is (-inf,+inf)
range is (-inf, ]
See explanation below to determine how I came to these results.
Completing the Square
When completing the square the value of "a" should not be any number other than 1; therefore, factor out the -2
Now divide by 2 and square the result. The equation should now look like this.
To move the out of the parenthesis you have to multiply it by -2
Factor within the parenthesis and clean up outside the parenthesis. The vector format of your function should look like below
To determine the y-int take the original function substitute 0 for x and you should get the y-int of 5
To get the x-int take the vertex format of the function and substitute 0 for y
Divide both sides by -2
the x-int = -1 ,
