Hi :

Just wondering Carrotsticks, do you think the person could be referring to
1. Draw the curve:
Which is a Hyperbola with the negative branch flipped upwards to become positive. Note that it has more 'extreme' values due to the fact that it's x squared not just x.
![]()
2. Shift it down by 4 units to acquire:
![]()
Quite possibly.Just wondering Carrotsticks, do you think the person could be referring to?
The x asymptotes are 2 and -2, the y asymptote is 0 (tell me if you don't know how I got this).I'm sorry, I was meaning 3 over the whole thing (x squared minus 4)
Symmetrical about the y axis means that the y axis cuts the function in half (well that's what it looks like).Thank you!I'm just wondering what 'symmetrical about the y axis and the origin' mean because it said in my textbook you have to find out if the fuction is odd/even/neither and if it's even then it's symmetrical about the y axis and if it's odd it's symmetrical about the origin. Thanks

if you were asked to answer that question, a quicker way would be to let y= f(x), and then find f(-x). if f(-x)=f(x) then it is an even function. if f(-x)=-f(x) then it is an odd function. if f(-x) equals to anything other than f(x) itself or -f(x) , it is neither even or odd .Thank you!I'm just wondering what 'symmetrical about the y axis and the origin' mean because it said in my textbook you have to find out if the fuction is odd/even/neither and if it's even then it's symmetrical about the y axis and if it's odd it's symmetrical about the origin.
