Will METAL!! For the given function, find the vertical and horizontal asymptote(s) (if there are any). f(x) = the quantity two x squared plus one divided by the quantity x squared minus four None x = 2, y = 2y = 0 x = 2, x = -2, y = 2 x = 2, y = 2, y = 1

    for \(\color{green}{\rm Vertical~ asy.}\) set the denominator equal to zero and then solve for the variable. for\(\color{green}{\rm Horizontal ~asy.}\) focus on highest degrees ~if the highest degree of the numerator is greater than the denominator then `No horizontal asy.` \[\color{reD}{\rm N}>\color{blue}{\rm D}\] example \[\large\rm \frac{ 7x^\color{ReD}{3} +1}{ 4x^\color{blue}{2}+3 }\] ~if the highest degree of the denominator is greater than the highest degree of the numerator then `y=0` would be horizontal asy. \[\rm \color{reD}{N}<\color{blue}{\rm D}\] example:\[\large\rm \frac{ 7x^\color{red}{2}+1 }{ 4x^\color{blue}{3}+3 }\] ~if both degrees are the same then divide the leading coefficient of the numerator by the leading coefficient of the denominator \[\rm \color{red}{N}=\color{blue}{D}\] \[\large\rm \frac{ 8x^\color{reD}{3}+1 }{ 4x^\color{blue}{3}+3 }\] \[\rm \frac{ 8x^3 }{ 4x^3 } =2\] horizontal asy. =2

    remember when we take square root we should get plus/minus answer \[\huge\rm \sqrt{x^2} = \pm x\]

    So it would be my third answer choice because that's the only one with a negative number.

    the horizontal asy is 2 because both degs on the top and bottom are even. Right?

    highest degree of both (Denominator and numberatr) are the same so just divide the leading coefficient |dw:1443803913846:dw|
