Answer:

Rational Function

Step-by-step explanation:

Gives the function:

f(x) = \frac{x-2}{3x-2x^2}

It has the following,

Domain

x∈ \mathbb{R} : x\neq 0, x\neq 3/2

Range

f \in \mathbb{R} : f \leq -1, f \geq -\frac{1}{9}

End behaviour

As xx \rightarrow \infty, y \rightarrow 0

Horizontal and Vertical Asymptote

Vertical x = 0, x=3/2

Horizontal y = 0

<em>x-intercept: (2,0)</em>

<em>y-intercept: none</em>

<em>**The Graph is in the annex</em>

F(x)= x(x+3)(x+1)(x-4) has zeros at x=-3
anygoal [31]

Answer:  C) Sometimes positive; sometimes negative

============================================================

Explanation:

Pick a value between x = -1 and x = 0. Let's say we go for x = -0.5

Plug this into f(x)

f(x) = x(x+3)(x+1)(x-4)

f(-0.5) = -0.5(-0.5+3)(-0.5+1)(-0.5-4)

f(-0.5) = -0.5(2.5)(0.5)(-4.5)

f(-0.5) = 2.8125

We get a positive value.

This shows that f(x) is positive on the region of -1 < x < 0

----------------

Now pick a value between x = 0 and x = 4. I'll use x = 1

f(x) = x(x+3)(x+1)(x-4)

f(1) = 1(1+3)(1+1)(1-4)

f(1) = 1(4)(2)(-3)

f(1) = -24

Therefore, f(x) is negative on the interval 0 < x < 4

----------------

In short, f(x) is both positive and negative on the interval -1 < x < 4

It's positive when -1 < x < 0

And it's negative when 0 < x < 4

Question:70% of x is 63. 1.Write an equation that shows the relationship of 70%, x, and 63. 2. Use your equation to find x. Show
a_sh-v [17]

"x" represents an unknown number, we know that 70% of x equals 63.

To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:

So the 70% of x can be calculated as:

\frac{70\cdot x}{100}=63

You can simplify this expression by solving the division

\begin{gathered} \frac{70}{100}x=63 \\ \frac{7}{10}x=63 \\ 0.7x=63 \end{gathered}

Then the expression that shows you the relationship is

0.7x=63

Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7

\begin{gathered} \frac{0.7x}{0.7}=\frac{63}{0.7} \\ x=90 \end{gathered}

The value of x is 90
