Question

REAL QUICK, SIMPLE ALGEBRA

Answer 1

convert f(x) into general/vertex form
f(x) = x^2 + 1x -6

Answer 2

vertex form i know is
y= a(x-h)^2 =+ k

Answer 3

so u can get a general idea where the x and y cordinates cross by solving for vertical and horzontal asymptotes

Answer 4

f(x) = x^2 + x - 6 is already in general form

Answer 5

i think complete the square gets u the vertex

Answer 6

to conver it tot the vertex form u must make it a perfect square

Answer 7

that is completing the square

Answer 8

can u show me how w the numbers its hard for me to picture this

Answer 9

i see where you're getting at but dont know what to plug in and solve for

Answer 10

that's where completing squares comes
f(x) = x^2 + x - 6
= (x + 1/2)^2 -6 - 1/4
= ( x + 1/2)^2 - 25/4

Answer 11

so after completing the sq, ( x + 1/2)^2 - 25/4 is the answer???

Answer 12

yes

Answer 13

it's the vertex format .... but do u know how to do it > i mean completing squares ?

Answer 14

yeah i know compl the sq but didnt kno i could do it for this example

Answer 15

so by that ur vertex is (-1/2, -25/4)

Answer 16

thank you sooooooooooooo much @fiberdust @***[ISURU]***

Answer 17

u understand how to get the vertical and horzontal asymptotes this helps
