f(2) when f(x) = 3x + 2
f−1(3) when f(x) = 2 x minus 7, all over 3
2y + 14 = 4y − 2

Answer 1

please help me

Answer 2

@freckles

Answer 3

do you know how to do these?

Answer 4

no

Answer 5

HI!!

Answer 6

hi

Answer 7

hi!!!!!!

Answer 8

\[f(2)\] when \[f(x)=3x+2\] is \[f(2)=3\times 2+2=8\]

Answer 9

how did you find that can you show your work so i can better understand it please

Answer 10

what grade r u in

Answer 11

i did this for algabra 1 in the 8th grade

Answer 12

\[f^{-1}(3)\] when \[f(x)=\frac{2x-7}{3}\]means solve \[\frac{2x-7}{3}=3\]

Answer 13

i can go get my book and explain it

Answer 14

@Barrelracing are you asking how i found \(f(2)\)?

Answer 15

How did you find anyone of the problems? like can you show the work please?

Answer 16

what math is this?

Answer 17

algebra 2

Answer 18

there are 3 questions
the first one is to find \(f(2)\) for \(f(x)=3x+2\)

Answer 19

ok gimme a sec to find my algebra 2 book

Answer 20

do do that, where you see an \(x\) replace it by a \(2\)

Answer 21

since \[f(x)=3x+2\] you have \[f(2)=3(2)+2=6+2=8\]

Answer 22

ok i got it

Answer 23

here is the page

Answer 24

it explains how to do it

Answer 25

makes since what about the other 2?

Answer 26

Misty i really need your help. i am not cheating for anything this is just an example in my lesson i didnt understand @misty1212

Answer 27

for anyone who needs the answer

f(x) = 3x + 2
f(2) = 3(2) + 2
6+2
8

2(3) - 7/3
6 - 7/3
-1/3
-3

2y + 14 = 4y - 2
16 = 2y
8 = y
