Solving Rational Inequalities and use sign diagram to sketch the graph. Image attached for better understanding.
Digiron [165]

Answer:

x ∈ (-∞, -1) ∪ (1, ∞)

Step-by-step explanation:

To solve this problem we must factor the expression that is shown in the denominator of the inequality.

So, we have:

x ^ 2-1 = 0\\x ^ 2 = 1

So the roots are:

x = 1\\x = -1

Therefore we can write the expression in the following way:

x ^ 2-1 = (x-1)(x + 1)

Now the expression is as follows:

\frac{(x-2) ^ 2}{(x-1) (x + 1)}\geq0

Now we use the study of signs to solve this inequality.

We have 3 roots for the polynomials that make up the expression:

x = 1\\x = -1\\x = 2

We know that the first two are not allowed because they make the denominator zero.

Observe the attached image.

Note that:

(x-1)\geq0 when x\geq-1

(x + 1)\geq0 when x\geq1

and

(x-2) ^ 2 is always \geq0

Finally after the study of signs we can reach the conclusion that:

x ∈ (-∞, -1) ∪ (1, 2] ∪ [2, ∞)

This is the same as

x ∈ (-∞, -1) ∪ (1, ∞)

Show all work to identify the asymptotes and zero of the faction f(x) = 4x/x^2 - 16.
Reptile [31]

Answer:

  • asymptotes: x = -4, x = 4
  • zeros: x = 0

Step-by-step explanation:

The vertical asymptotes of the rational expression are the places where the denominator is zero:

  x^2 -16 = 0

  (x -4)(x +4) = 0 . . . . . true for x=4, x=-4

  x = 4, x = -4 are the equations of the vertical asymptotes

__

The zeros of a rational expression are the places where the numerator is zero:

  4x = 0

  x = 0 . . . . . . divide by 4

WHO IS GOOD AT MATH??! PLEASE HELP!
Galina-37 [17]

Answer:

See below.

Step-by-step explanation:

Equation of parabola:

y = some expression in x^2

To translate the parabola vertically, substitute y with y - k.

The translation is k units vertically. If k is positive, the translation is up. If k is negative the translation is down.

Example 1:

original parabola: y = x^2 - 2x + 5

To translate it 3 units up, we need k = 3.

Substitute y with y - 5 to get

y - 3 = x^2 - 2x + 5

y = x^2 - 2x + 8 is the equation of the parabola translated 3 units up.

Example 2:

original parabola: y = 2x^2 + 4x - 6

To translate it 5 units down, we need k = -5.

Substitute y with y - (-5), or y = 5 to get

y + 5 = 2x^2 + 4x - 6

y = 2x^2 + 4x - 11

y = 2x^2 + 4x - 11 is the equation of the parabola translated 5 units down.
