Question

Given the function f(x) = −2x + 8, find x if f(x) = 14

Answer 1

14 = -2x +8
2x = -6
x = -3

Answer 2

petite is wrong

Answer 3

the function f(x) = -2(14)+8 = -20, so f(x) = -20 . (I did this last chapter in precalculus)

Answer 4

did you read the question?

Answer 5

Just replace the X with 14 in the equation and replace f(x) so it's y instead.

Answer 6

no petite is the only one who is correct actually

Answer 7

it says f(x) is 14, find x ,not x is is 14

Answer 8

OH

Answer 9

yeah

Answer 10

my bad, ignore me, i misread the question. im always trying to help but im always wrong, i might as well give up now :)

Answer 11

\[f(14)=-2(14)+8\]
\[f(14)=-28+8\]
\[f(14)=-20\]

Answer 12

you have it backwards overachiever

Answer 13

f(x) = 14 ; not f(14) ....

Answer 14

just follow petite's work and answer and you'll be fine op

Answer 15

oh sorry i read it wrong too

Answer 16

f(x) = -2x + 8
|
14 = -2x + 8 ; is the correct way to solve it :)

Answer 17

fenwick, being wrong is fine :) as long as we learn from our mistakes

Answer 18

sometimes that's the best way to learn
