Well that depends on what graphs you were given to check... Personally I would have just gone...
Hence asymptotes at . Gets very small when
Which should be enough but you could also notice it will cross the y-axis at y=-1.
My teacher likes to kick off a new unit by making us do a question on our own so I am a little confused..
Reciprocal of a Quadratic Function
I have a question that shows 3 graphs - and an equation of f(x)= 1/x^2-1
The question is "which graph shows f(x)= 1/x^2-1"
I've already found my answer - but it was lengthy; I found the domain - vertical asymptotes/end behaviours/horitzontal asymptotes/x+yintercepts/than graphed it on my own
My question for you guys is - is there a way to figure out which graph represents f(x)= 1/x^2-1 without having to do all those steps? By just looking at it..?
Thanks for your patience & time.
