What is the range of the function f(x) = |x + 4| + 2?
storchak [24]

\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}

<h3>Given:</h3>

▪ \longrightarrow \sf{f(x) = |x + 4| + 2}

You need to remember that the form of an Absolute Value Function is:

•<em> </em><em>For the vertex:</em>

\small\longrightarrow \sf{H= \:  \: x -coordinate}

\small\longrightarrow \sf{K= y-coordinate}

• <em>For the</em> definition:

If "a" is positive (+) , then the range of the function is:

\small\longrightarrow \sf{R:y \:   \underline >  \:  k}

If "a" is negative (-), the range of the function is:

\small\longrightarrow \sf{R: y  \: \underline  <  \: k}

In this case we can identify that:

\small\longrightarrow \sf{a = 1}

\small\longrightarrow\sf{a = 2}

\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}

\large \bm{R: {f(x)  \in ℝ | f(x)   \underline >   2}}

The standard formula for the volume of a rectangular pyramid is . If the pyramid is scaled proportionally by a factor of k, its
PolarNik [594]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The volume of a rectangular pyramid is equal to

V=\frac{1}{3}LWH

where

L is the length of the rectangular base

W is the width of the rectangular base

H is the height of the pyramid

If the pyramid is scaled proportionally by a factor of k

then

the new dimensions are

L=kL

W=kW

H=kH

substitute and find the new Volume V'

V'=\frac{1}{3}(kL)(kW)(kH)

V'=\frac{1}{3}(k^{3})LWH

V'=(k^{3})\frac{1}{3}LWH

V'=(k^{3})V

The new volume is equal to the scale factor k elevated to the cube multiplied by the original volume

Suppose you have a bag of red, blue, and yellow marbles. If the probability of picking a red marble is1/6 and the probability of
yulyashka [42]
The probabilities of picking a red, blue, and yellow marble must be equal to 1. so

P(R)+P(Y)+P(B)=1

1/6+1/2+P(B)=1  making all terms have a common denominator of 6 we have:

1+3+6P(B)=6

4+6P(B)=6

6P(B)=2

P(B)=2/6

P(B)=1/3
