y intercept at 2
Transcript text: Write an equation for a rational function with:
Vertical asymptotes at $x=-2$ and $x=2$
$x$ intercepts at $x=6$ and $x=-4$
$y$ intercept at 2
\[
y=
\]
$\square$
Solution
Solution Steps
Step 1: Construct the Denominator
The denominator is constructed based on the given vertical asymptotes: $(x + 2) * (x - 2)$.
Step 2: Construct the Numerator
The numerator is constructed based on the given x intercepts: $(x - 6) * (x + 4)$.
Step 3: Determine the Constant $k$
Given a y intercept of 2, substitute $x = 0$ into the equation and solve for $k$ using the y intercept value. This gives $k = 0.33$.
Final Answer:
The constructed rational function is $y = 0.33 \cdot \frac{(x - 6) * (x + 4)}{(x + 2) * (x - 2)}$, rounded to 2 decimal places.
