Question

Perform the requested operation or operations.

f(x) = x minus five divided by eight.; g(x) = 8x + 5, find g(f(x)).

@LXelle

Answer 1

\[f(x)= \frac{ (x-5) }{ 8}\]
\[g(x)= 8x+5\]

Answer 2

g is the first function that you wanted. so what you do is you substitute f(x) into g(x). get what i mean?

Answer 3

\[g(f(x)) = 8(\frac{ x-5 }{ 8 }) + 5\]

then you solve it from there.

Answer 4

is it going to equal g(f(x)) = 8x + 35 @LXelle

Answer 5

or i can say x-5/8

Answer 6

No, no. Dont assume.

Answer 7

Is it g(f(x)) = x - five divided by eight.

Answer 8

No, never. How are you getting back the f(x)?

Answer 9

g(f(x)) = x that might be the answer

Answer 10

\[g(f(x))=8(\frac{ x-5 }{ 8 })+5\]

Answer 11

From there cancel of the 8 leaving only \[x-5 + 5\]

Answer 12

Therefore what you get is only x left.

Answer 13

Do you know why I cancel the 8s?

Answer 14

no why

Answer 15

you factorize. 8 divided by 8 is?

Answer 16

1

Answer 17

what is left is gonna be 1(x-5)+5 Agree?

Answer 18

so when you open the bracket you get x-5+5 agree?

Answer 19

x-10

Answer 20

nooooo. -5+5 is not 10.

Answer 21

0

Answer 22

Yeah so you got your answer.
