Question

Write the standard equation for each Hyperbola.

1. x2 - 100y2 = 100

2. 4y2 - 25x2 = 100

3. vertices (-6, 0) ( 6, 0) and

focus (-8, 0) ( 8, 0)

4. vertices ( 0, -12) ( 0, 12) and

co-vertices (-11, 0) (11, 0)

Answer 1

Write the standard equation of each Ellipse. Find the center, vertices, co-vertices and foci.

1. 25x2 + 9y2 = 225

2. 49x2 + y2 = 49

3. x2 - 2x + 9y2 - 8 = 0

4. x2 + 4y2 - 18x -8y + 81 = 0

Answer 2

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.



1) -2, -1, 1

2) i, 4

3) i, 2 - √3

4) 1, 4, 1 + √2

Answer 3

f(x) = anxn + an - 1...+ a1 + a0:

If n is odd and an > o, then f(x) approaches _____as x approaches positive infinity and f(x) approaches _____ as x approaches negative infinity.
If n is odd and an < 0, then f(x) approaches _____ as x approaches positive infinity and f(x) approaches _____ as x approaches negative infinity.
If n is even and an > 0, then f(x) approaches _____ as x approaches positive infinity and f(x) approaches _____ as x approaches negative infinity.
If n is even and an < 0, then f(x) approaches _____ as x approaches positive infinity and f(x) approaches _____ as x approaches negative infinity.
