#

For 6: find g(5) value, use that value to find f

#

@mossy owl

#

What's g(5)?

mossy owl Jan 18, 2023, 11:48 PM

#

is it 8?

whole basin Jan 18, 2023, 11:48 PM

#

Correct

#

So f(g(5))=f(8)

#

Now find the value of f for 8

mossy owl Jan 18, 2023, 11:50 PM

#

9?

whole basin Jan 18, 2023, 11:50 PM

#

Yep. So f(g(5))=9

#

Try problem 10 now

mossy owl Jan 18, 2023, 11:52 PM

#

is 10 f(f(1))=6

whole basin Jan 18, 2023, 11:53 PM

#

No, take it step by step

#

So your first step is to evaluate the innermost value

#

Which is f(1)

#

When you find that value, you can plug it in and find the outer value

#

So you have f(f(1)). We find what f(1) is and we substitute the result into f(f(1))

#

For problem 6 you did this:
f(g(5)) = f(8) = 9

#

Try again and try writing it out like that

mossy owl Jan 19, 2023, 12:00 AM

#

F(f(1))=f(6)=36?

whole basin Jan 19, 2023, 12:01 AM

#

Is f(6) = 36?

#

The table says different for f(6)

mossy owl Jan 19, 2023, 12:01 AM

#

yes

#

How

#

Is it 0?

whole basin Jan 19, 2023, 12:02 AM

#

f(5) is 0

mossy owl Jan 19, 2023, 12:02 AM

#

12?

#

No way its not 12

whole basin Jan 19, 2023, 12:03 AM

#

How did you get 12

#

And 36

#

And 0

mossy owl Jan 19, 2023, 12:04 AM

#

F(f(1))=f(6)=2

#

Thats my final guess im jus stupid asf rn

whole basin Jan 19, 2023, 12:05 AM

#

That's a good guess

mossy owl Jan 19, 2023, 12:05 AM

#

Im wrong

#

😭😭

whole basin Jan 19, 2023, 12:06 AM

#

No, you're right

mossy owl Jan 19, 2023, 12:06 AM

#

aint no way

whole basin Jan 19, 2023, 12:06 AM

#

It's your best guess so far

mossy owl Jan 19, 2023, 12:06 AM

#

lolllll

#

I think i get it now

whole basin Jan 19, 2023, 12:06 AM

#

Do you get it now?

#

Good

mossy owl Jan 19, 2023, 12:07 AM

#

Yes lmaoo

whole basin Jan 19, 2023, 12:07 AM

#

14 same thing but we use graphs

#

f(g(1))

#

How much is g for x=1?

mossy owl Jan 19, 2023, 12:08 AM

#

ur asking how much one g is for x=1?

whole basin Jan 19, 2023, 12:14 AM

#

Im asking you the value g(x) for x=1

mossy owl Jan 19, 2023, 12:22 AM

#

#

bro im lost would it not jus be one

whole basin Jan 19, 2023, 12:28 AM

#

No, your x values are on the horizontal line (x-axis) and you read the value of the function on the vertical line (y-axis)

#

#

What I drew there is g(1)

mossy owl Jan 19, 2023, 12:30 AM

#

ohhhhhghgggg

#

Ohhhhhhh^*

whole basin Jan 19, 2023, 12:30 AM

#

For value x=1, g(x) or g(1) is 3

#

Back to our problem, we had f(g(1))

#

Now we know g(1) is 3

#

So we're looking for f(3)

#

What is f(3)?

mossy owl Jan 19, 2023, 12:35 AM

#

it would be 2?

#

or 3

#

i will go with 2

whole basin Jan 19, 2023, 12:35 AM

#

2 or 3?

#

Be 100% sure

mossy owl Jan 19, 2023, 12:41 AM

#

2

whole basin Jan 19, 2023, 12:44 AM

#

Good

#

Do 18 now

mossy owl Jan 19, 2023, 12:58 AM

#

wait for 14

#

would i write it like

#

g(1)=3 f(1)=2

#

or would i writr it

#

like how i used to on the previous problems

whole basin Jan 19, 2023, 1:01 AM

#

f(g(1))=f(3)=2

#

f(1) is not 2

#

f(3) is 2
