QUESTION 2
The given function is
This function has a horizontal asymptote of .
To find the y-intercept, we put into the function to get;
QUESTION 3
The given function is

To find the y-intercept, we put into the function to get;
QUESTION 4
The given function is
This function has a horizontal asymptote of .
To find the y-intercept, we put into the function to get;
Notice that
(1 - <em>x</em>)⁵ (1 + 1/<em>x</em>)⁵ = ((1 - <em>x</em>) (1 + 1/<em>x</em>))⁵ = (1 - <em>x</em> + 1/<em>x</em> - 1)⁵ = (1/<em>x</em> - <em>x</em>)⁵
Recall the binomial theorem:
Let <em>a</em> = 1/<em>x</em>, <em>b</em> = -<em>x</em>, and <em>n</em> = 5. Then
We get an <em>x</em> ³ term for
2<em>k</em> - 5 = 3 ==> 2<em>k</em> = 8 ==> <em>k</em> = 4
so that the coefficient would be
