Chapter 11: Q. 163E (page 1134)

In the following exercises, graph.
$\frac{{(y + 4)}^{2}}{25} - \frac{{(x + 1)}^{2}}{36} = 1$

Short Answer

Expert verified

The graph is as below

Step by step solution

Step 1. Given information

The equation is $\frac{{(y + 4)}^{2}}{25} - \frac{{(x + 1)}^{2}}{36} = 1$

Draw the graph.

Step 2. Calculation

The y² term is positive, the transverse axis is vertical.

The hyperbola opens up and down.

Find the centre

Compare the equation with standard form $\frac{{(y + k)}^{2}}{a^{2}} - \frac{{(x + h)}^{2}}{b^{2}} = 1$

So, $(h, k) = (- 1, - 4)$ and $a^{2} = 25 \Rightarrow a = \pm 5$

$b^{2} = 36 \Rightarrow a = \pm 6$

Sketch the rectangle that goes through the points 5 units above/below the centre

6 units left/right of centre

Step 3. Draw the graph

Sketch the asymptotes through the diagonals of the rectangle.

The graph is
