Chapter 11: Q. 167E (page 1134)

In the following exercises, graph $\frac{{(x - 3)}^{2}}{25} - \frac{{(y + 2)}^{2}}{9} = 1$

Short Answer

Expert verified

The graph of equation $\frac{{(x - 3)}^{2}}{25} - \frac{{(y + 2)}^{2}}{9} = 1$ is as below

Step by step solution

Step 1. Given information

The equation is $\frac{{(x - 3)}^{2}}{25} - \frac{{(y + 2)}^{2}}{9} = 1$

Draw the graph.

Step 2. Calculation

The x² term is positive, the transverse axis is horizontal.

The hyperbola opens left and right .

Find the centre

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

So, $(h, k) = (3, - 2)$ and $a^{2} = 25 \Rightarrow a = \pm 5$ and $b^{2} = 9 \Rightarrow b = \pm 3$

Sketch the rectangle that goes through the points 5 units left/right of centre 3 units above/ below the centre.

Step 3. Draw the graph

Sketch the asymptotes and draw the graph
