Answer:

987.76 Hz

Step-by-step explanation:

You have B4's frequency of 493.88 Hz and you want to know the frequency of the note one octave <u>above</u> B4.

When you go up an octave, you double the original frequency. When you go down an octave, you divide the original frequency by two.

So, since B4's frequency is about 493.88 Hz, an octave above would be 2 x 493.88 Hz or 987.76 Hz

If we were looking for an octave below B4, we would divide 493.88 Hz by 2 to get 246.94 Hz.

The function of x is $\bold{\frac{-1x}{2}}$ .

<u>SOLUTION:</u>

Given that, we have to write a linear function f with function of (-4) =2 and function of 6=(−3).

Now, let the linear function be $\text{function of x}=a x+b$

Then, function of -4 = $a(-4)+b \rightarrow 2=-4 a+b \rightarrow b=2+4a \rightarrow (1)$

And, function of 6 = $a(6)+b \rightarrow-3=6 a+b \rightarrow b=-3-6a \rightarrow (2)$

On equating (1) and (2) to find the value of a,

$2+4a=-3-6a$

On grouping the common terms,

$4a+6a=-3-2 \rightarrow 10a=-5 \rightarrow a=\frac{-5}{10}$

$\Rightarrow a=\frac{-1}{2} \rightarrow (3)$

On substituting the value of (3) in (1) we get,

$b=2+4a \rightarrow b=2+4\times\frac{-1}{2} \rightarrow b=2+\frac{-4}{2} \rightarrow b=2+(-2)$

$\Rightarrow b=0$

So, the function of x = $\frac{-1x}{2}+0$

Answer:

Step-by-step explanation:

The parent function y = | x | has it's vertex at the origin

Here the vertex is at (- 4, 2)

That is shifted 4 units to the eft of the origin, thus

y = | x + 4 |

Shifted 2 units up is denoted by + 2, thus

y = | x + 4 | + 2 → E
