Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

How do you find the intersection of two sets?

Vlad [161]

To find the intersection of these two sets, we need to find out what elements they have in common. The numbers 3, 4, 5 are elements of both sets, therefore theintersections of A and B is {3. 4. 5].

Find the length of DE.

Amanda [17]

I think same as BC because it seem like its a reflected problem and x would be 23 and if 23-5 that would be 18 I think.

What is the range of g(x)=-1/2|x-6| + 1

Olin [163]

Answer:

Range : y >= 1

Step-by-step explanation:

What is the range of g(x)=-1/2|x-6| + 1

This absolute value function has a V shape

the vertex is at (6, 1)

so the range would consist of values from y = 1 and upward
