    Horizontal asymptote is y=k, if the leading coefficient of the numerator divided by the leading coefficient of the denominator is a constant k. Example: y=(2x-3)/(x-2), k=2x/x=2, so horizontal asymptote is at y=2. In this case, x^2/x=x, so the asymptote is a slanting one, y=x.

    bec ~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 \[\large\rm \frac{ 7x^\color{ReD}{3} +1}{ 4x^\color{blue}{2}+3 }\] use the example provided by math to find horizontal asy.

    Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. f(x) = quantity x minus seven divided by quantity x plus two. and g(x) = quantity negative two x minus seven divided by quantity x minus one.

    Example: f(x)=log(x) g(x)=e^x f(g(x))=log(e^x))=x, so g is the inverse of f (and vice versa) Another example f(x)=2x+3 g(x)=(x-3)/2 f(g(x))=2((x-3)/2)+3=x-3+3=x g(f(x))=((2x+3)-3)/2=2x/2=x so g is the inverse of f (and vice versa)

    Do you mean this? "f(x) = quantity x minus seven divided by quantity x plus two. and g(x) = quantity negative two x minus seven divided by quantity x minus one." f(x)=(x-7)/(x+2) g(x)=(-2x-7)/(x-1) Except that the question should have read: "f(x) = quantity x minus seven \(\color{red}{all}\) divided by quantity x plus two. and g(x) = quantity negative two x minus seven \(\color{red}{all}\) divided by quantity x minus one." It shows that the person who made up the problem does not work daily with algebra.
