Answer:

Explanation:

We can factor the numerator and denominator as;

(

x

−

2

)

(

x

−

1

)

2

x

(

x

−

1

)

We can now cancel common term in the numerator and denominator:

(

x

−

2

)

(

x

−

1

)

2

x

(

x

−

1

)

⇒

x

−

2

2

x

However, we cannot divide by

0

so we must exclude:

2

x

=

0

⇒

x

=

0

and

x

−

1

=

0

⇒

x

x

x

=

Where:

x

≠

0

and

x

≠

1

Or

Where:

and

A hyperbola centered at the origin has a vertex at (0,−40) and a focus at (0, 41).

aniked [119]

$\frac{(x-h)^{2} }{a^{2} } - \frac{(y - k)^{2} }{b^{2} } = 1$

$\frac{(x-0)^{2} }{40^{2} } - \frac{(y - 0)^{2} }{b^{2} } = 1$

a² + b² = c²

40² + b² = 41²

b² = 41² - 40²

b² = 1681 - 1600

b² = 81

b = 9

slope (m) of asymptote = $+/-\frac{y}{x} = +/-\frac{b}{a} = +/-\frac{9}{40}$

y-intercept (b) = 0 since the center is at the origin

Answer: y = $\frac{9}{40}x$ and y = $-\frac{9}{40}x$
