Write the function notation for the transformation that would change f(x) to have a vertical

koban [17]

Function is $4 - \frac{f(x)}{8}$ .

Step-by-step explanation:

We have a function notation for the transformation that would change f(x) to have a vertical compression by a factor of $\frac{1}{8}$ , reflection over the x axis, up 6 and right 2.

Step 1:

Vertical compression by a factor $\frac{1}{8}$ , this means decreasing value of function by a factor of $\frac{1}{8}$ . Function becomes $\frac{f(x)}{8}$ .

Step 2:

Reflection over x-axis means rotating f(x) by 180° over origin . Function now is $-\frac{f(x)}{8}$ .

Step 3:

Up 6 , means value of function is increased by 6 , Function now is $\frac{-f(x)}{8} + 6$ .

Step 4:

Right 2, means shifting function to 2 units on right side i,e, on x-axis.

∴Function finally becomes, $\frac{-f(x)}{8} +6 - 2$ which is $4 - \frac{f(x)}{8}$ .

In radian measure, the angles of a 45-45-90 triangle are:

jeka94

Answer:

The answer is the option A $\frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}$

Step-by-step explanation:

we know that

The measure of $\pi$ radians is equal to $180\°$

so by proportion

Find the measure in radians of $45\°$

$\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{45}\frac{radians}{degrees}\\ \\x=(45/180)*\pi \\ \\x=\frac{\pi}{4}$

Find the measure in radians of $90\°$

$\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{90}\frac{radians}{degrees}\\ \\x=(90/180)*\pi \\ \\x=\frac{\pi}{2}$

therefore

In radian measure the angles are

$\frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}$

Answer:

$g(x)=x+8$

Step-by-step explanation:

Translating a function up is very simple, all you need to do here is add 8.

If you want to think of it logically,

$f(x)=x$

the whole right side of the function here can be our output. If x is 8, then the output, or height, is also 8. if you wanted to translate that up to 10, you'd simply need to add 2 to it, meaning $x+2$ . Then, at any given point on the function, it'd be 2 higher than it would be otherwise.
