What are the vertices of the hyperbola given by the equation?
first you need to find the center of the hyperbola. do you know what this is?
do you know how to find the center of a hyperbola?
Not exactly? can you show me :)
the standard form of a hyperbola is (check image attached) where (h, k) is the centre.
so in this case what will be our centre if you compare it to your hyperbola equation?
wait am i getting the values for the variables from the original? :/
we are trying to get to find the vertices. you have your hyperbola equation. so i gave you the standard form of a hyperbola. to find the vertices, first we find the center. which is (h,k) from the standard form of a hyperbola that i gave you. so now compare this to YOUR hyperbola equation and get the centre (h,k). do you understand now?
-5,-8?
no. close. but wrong answer. the center is (5, 8)
so now that we have the center (h,k). for your hyperbola. the vertices will be (h + a, k) and (h - a, k). So now if you work this out. you can find the vertices of your hyperbola :)
(5+9,8) and (h-9,8)?
(5+9,8) and (5-9,8)? **
no. first what is the value of a?
look carefully at the denominator of the x term. it's \[a ^{2}\]. but we are interested in \[a\]
9?
no. \[a ^{2} = 9\]
what now then will be our value for \[a\] ?
3?
nice. so now find (h + a, k) and (h - a, k) which will be our vertices for this hyperbola :)
5+3, 8) and (h-3, 8)?
good. but what is the value of \[h\]?
comparing to the standard form of the hyperbola?
5+3, 8) and (5-3, 8)?
super! so now write it well as points. get rid of the "+" sign
2,8 and 8,8?:)
can you find this in the possible answers? if you can, that's your answer ;)
thankkks!
its A :)
you're welcome ;)
