Answer:

f(2.1) = 0.512195

f(2.05) = 0.506173

f(2.01)=0.501247

f(2.001) = 0.500125

f(2.0001) = 0.500012

f(1.9) = 0.487179

f(1.95) = 0.493671

f(1.99) = 0.498747

f(1.999) = 0.499875

f(1.9999) = 0.499987

Step-by-step explanation:

Given

f(x) = \frac{x^2 - 2x}{x^2 - 4}

Solve for f(x) for all given values of x

First, we need to simplify f(x)

f(x) = \frac{x^2 - 2x}{x^2 - 4}

f(x) = \frac{x(x - 2)}{x^2 - 2^2}

f(x) = \frac{x(x - 2)}{(x- 2)(x + 2)}

f(x) = \frac{x}{x + 2}

When x = 2.1

f(x) = \frac{x}{x + 2}

f(2.1) = \frac{2.1}{2.1 + 2}

f(2.1) = \frac{2.1}{4.1}

f(2.1) = 0.512195

When x = 2.05

f(x) = \frac{x}{x + 2}

f(2.05) = \frac{2.05}{2 + 2.05}

f(2.05) = \frac{2.05}{4.05}

f(2.05) = 0.506173

When x = 2.01

f(x) = \frac{x}{x + 2}

f(2.01)=\frac{2.01}{2.01 +2}

f(2.01)=\frac{2.01}{4.01}

f(2.01)=0.501247

When x = 2.001

f(x) = \frac{x}{x + 2}

f(2.001) = \frac{2.001}{2.001 +2}

f(2.001) = \frac{2.001}{4.001}

f(2.001) = 0.500125

When x = 2.0001

f(x) = \frac{x}{x + 2}

f(2.0001) = \frac{2.0001}{2.0001 + 2}

f(2.0001) = \frac{2.0001}{4.0001}

f(2.0001) = 0.500012

When x = 1.9

f(x) = \frac{x}{x + 2}

f(1.9) = \frac{1.9}{1.9 + 2}

f(1.9) = \frac{1.9}{3.9}

f(1.9) = 0.487179

When x = 1.95

f(x) = \frac{x}{x + 2}

f(1.95) = \frac{1.95}{1.95 + 2}

f(1.95) = \frac{1.95}{3.95}

f(1.95) = 0.493671

When x = 1.99

f(x) = \frac{x}{x + 2}

f(1.99) = \frac{1.99}{1.99 + 2}

f(1.99) = \frac{1.99}{3.99}

f(1.99) = 0.498747

f(x) = \frac{x}{x + 2}

When x = 1.999

f(x) = \frac{x}{x + 2}

f(1.999) = \frac{1.999}{1.999 + 2}

f(1.999) = \frac{1.999}{3.999}

f(1.999) = 0.499875

When x = 1.9999

f(x) = \frac{x}{x + 2}

f(1.9999) = \frac{1.9999}{1.9999 + 2}

f(1.9999) = \frac{1.9999}{3.9999}

f(1.9999) = 0.499987

<em>Note that all values of f(x) are approximated to 6 decimal places</em>

Which of the binomials below is a factor of this trinomial? x^2 + 3x - 4A. x+4B. x+8C. x-4D. x^2+4
Usimov [2.4K]

Given:

The equation is:

x^2+3x-4

Find-:

Binomials factor of the equation

Explanation-:

The quadratic equation,

x^2+3x-4

Solve for factor

\begin{gathered} =x^2+3x-4 \\  \\ =x^2+4x-x-4 \\  \end{gathered}

Then the factor is:

\begin{gathered} =x^2+4x-x-4 \\  \\ =x(x+4)-1(x+4) \\  \\ =(x+4)(x-1) \end{gathered}

So, the factor is x + 4

For which interval is the function increasing<br><br> Choose two answers that are correct
kaheart [24]

Answer:

-8 ≤ x ≤ - 6

2 ≤ x ≤  6

Step-by-step explanation:

Increasing part of the function can be easily determined from the graph.

Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing.

From the graph, we see that the function is increasing in the interval $ - 8 \leq \ x \leq -6 $

Between -6 and -4, the graph is constant and takes the value 4.

After that it decreases till x = -2 until it becomes a constant function again on x = 2.

Then, it again increases from x = 2 till x = 6. This is represented by the interval

$ 2 \leq x \leq 6 $.

Then it again decreases.

So, OPTION A and C are the answers.
