Chapter 11: Q. 309 (page 1159)

In the following exercises, identify the type of graph.
$(a) 16 y^{2} - 9 x^{2} - 36 x - 96 y - 36 = 0 (b) x^{2} + y^{2} - 4 x + 10 y - 7 = 0 (c) y = x^{2} - 2 x + 3 (d) 25 x^{2} + 9 y^{2} = 225$

Short Answer

Expert verified

The equation represents

(a) hyperbola

(b) circle

(d) ellipse

Step by step solution

Step 1. Given Information

The given equations are

$(a) 16 y^{2} - 9 x^{2} - 36 x - 96 y - 36 = 0 (b) x^{2} + y^{2} - 4 x + 10 y - 7 = 0 (c) y = x^{2} - 2 x + 3 (d) 25 x^{2} + 9 y^{2} = 225$

Part (a) Step 1. Explanation

From the given equation it is very clear that $x^{2} a n d y^{2}$ terms have different sign and different coefficient. So, the equation represents the hyperbola.

Part(b) Step 1. Explanation

From the given equation it is very clear that $x^{2} a n d y^{2}$ terms have samesign and samecoefficient. So, the equation represents the Circle.

Part(c) Step 1. Explanation

From the given equation it is very clear that one variable $y$ is squared . So, the equation represents the parabola.

Part (d) Step 1. Explanation

From the given equation it is very clear that $x^{2} a n d y^{2}$ terms have same sign and different coefficient. So, the equation represents the ellipse.
