Answer:

  B.  f(x) = 3/(x^2 +2x +1)

  E.  f(x) = 5/(3+x)

Step-by-step explanation:

The above functions have denominators that are zero at one point. For B, that point is x=-1; for E, that point is x=-3. When the denominator is zero, the function is undefined, so the corresponding x-value must be excluded from the domain.

__

As written, choice D also qualifies. This is because the function written in the answer list here is ...

f(x)=\dfrac{1}{x^2}+5x+4

It will be undefined for x=0.

<em>Comment on writing rational functions</em>

When the division symbol (/ or ÷) is used with a denominator that is a product or sum, that product or sum must be enclosed in parentheses. When the expression is typeset, the division bar acts as a grouping symbol. When the expression is written in text, a grouping symbol, such as parentheses, must be added.

Lines x and y are parallel and are cut by the transversal b. If the measure of angle 1 is 57°, what is the measure of angle 6? E
lana [24]

Answer:

\angle6=123

Step-by-step explanation:

Given

Lines x and y

Transversal b

\angle 1 = 57

Required

Find \angle 6

From the attachment, \angle1 and \angle7 are vertically opposite.

This means that

\angle 1 =\angle 7 = 57

Similarly

\angle 7  and \angle 6 are supplementary angles

So:

\angle7 + \angle6=180

Make \angle6 the subject

\angle6=180-\angle7

\angle6=180-57

\angle6=123

The relationship between \angle1 and \angle6 is that they are supplementary angles because:

\angle6+ \angle1=180

If the parent function is \root(3)(x), describe the translation of the function y=\root(3)(x+4)-3
xeze [42]

The parent function moves 4 units right and 3 units down. This is a translation by the vector.

According to the question,

Transformation \sqrt[3]{x} maps  onto \sqrt[3]{x+4} -3 . Take f(x) =  \sqrt[3]{x} and f(x+4)=\sqrt[3]{x+4}.

f(x) =  \sqrt[3]{x}

f(x+4)=\sqrt[3]{x+4}

f(x+4) - 3=\sqrt[3]{x+4} - 3

Analyze the function to see the translations. f(x-4) corresponds to a horizontal translation 4 units in the positive 'x' direction. f(x)-3 corresponds to a vertical translation 3 units in the negative 'y' direction.

Hence, the parent function moves 4 units right and 3 units down. This is a translation by the vector.
