Give an example of a function g(x) such that has vertical asymptotes at x = −1 and x = 2.
BigorU [14]

Answer:

\frac{69420}{(x+1)(x-2)}

Step-by-step explanation:

An asymptote of a vertical line is one that the graph can't exactly reach, but can get as close as you want it to be (as long as the distance is not 0), while the x- or y-coordinates tend to plus/minus infinity. An example of where this happens is when filling in the x-value would result in a zero in the denominator, hence the answer.

Solve the equation: 2/3x+1/4=3
Lady_Fox [76]

Answer:

x = 33/8

Step-by-step explanation:

2/3 x + 1/4 = 3

Subtract 1/4 from both sides.

2/3 x = 3 - 1/4

2/3 x = 12/4 - 1/4

2/3 x = 11/4

Multiply both sides by 3/2.

3/2 * 2/3 x = 3/2 * 11/4

x = 33/8

What is the equation for a circle with a radius of 10 and a center at (11, -2)?
Norma-Jean [14]
The equation of a circle with centre (a, b) and radius r is (x - a)^2 + (y - b)^2 = r^2.
So here it is:
(x-11)^2 + (y+2)^2 = 100
