Thanks so much!

17 is the answer 

f(f(x))  = 2   when  f(x)   = -3 , 0   and 3

When f(x) = -3.....the value of x is not defined

When f(x)  = 0, x = -4

When f(x)  = 3, x = -2 and 4

So....the solutions are x= -4, x = -2  and x = 4

\((10^{10})^{100}\)

When you raise an exponent to an exponent, multiply the exponents.

\(= 10^{10*100} \\ = 10^{1,000}\)

And 10^1,000 is a 1 with 1,000 zeros after it. I'm not going to type all that lol.

use the formula

maybe look it up ya silly goose

just type them in  

here is an image to cheer you up

A sparkly lake high in the mountains was what I was thinking of but I kinda like to have one with friends and family. But that I would like to have one for myself and only bring my special people with me.

that really helped!

h(x - 3) shifts the graph 3 units to the right....so...

The point (-2.3)  will shift to (1,3)  which is also on the original graph.....and the sum of the coordinates will  = 1 + 3  = 4

Okie... l'm sure the forum needed not of a superhero... but a decent human being. You filled that role my friend. As did many.

Come on guest, I always get upset when people do this.

You are meant to be using us to help you learn not to do all your homework for you!!

Ask one question, ask questions about the answer, say thank you, give points, think about the answer, then try the next one by yourself before you ask how to do it.

That is the polite way and that is the way that will help you most! 

If I had my way, questions like this would be blocked but this is a democratic system and some people just like to show off that they can do it so I will leave it alone.  Pity, I would like this site to teach you, not just provide a cheating tool for you to use.

Mach varies with altitude, temperature, humidity due to the changes in air density which affects the speed of sound

At sea level with dry air and 20 c   Mach 1 = 768 mph

768 mph x 100,000

768*100000 = 76800000 mph

Thanks Melody and CPhill!

This can be a little confusing....

f(f(x))   = 3  when f(x)  = -3 and f(x)  = 1   and f(x) = 4.5

When f(x)  = -3   the value of x is off the graph

And when f(x)  = 1, x = -1

And when f(x) = 4.5 , x = 2.5

So x = -1   and x = 2.5

That one made me think !

I draw a horizonatal line at y=3

The graph crosses this at thre points,

Approx     x=-3,     x=1    and     x=4.5

So when does 

f(x)=-3    NEVER

f(x)=1     at   x=-1

f(x)=4.5   at   x=2.5

So there are 2 solutions.    x=-1    and      x =  2.5

I'm sad. ​

I'm hungry! I'm waiting for my mom to get back from the grocery store so I can eat some spongebob macaroni and cheese! 

n + 10 = 40

Subtract 10 from both sides.

n = 40 - 10

n = 30

Replace "n" with 30, since n = 30.

n - 25

30 - 25 = 5
