Question

Consider the function represented by the equation x – y = 3. What is the equation written in function notation, with x as the independent variable?

f(x) = y + 3
f(x) = –y – 3
f(x) = –x + 3
f(x) = x – 3

Answer 1

so like a first step do you can separate the y in a part of this equation ? - better in the left part

Answer 2

yes

Answer 3

so this is your equation

x -y = 3

to separate the y on the left part like a first step you need subtract from both sides an x
so in this way what will get ?

Answer 4

please collaborate

Answer 5

f(x) = –y – 3?

Answer 6

no i ve said above subtract an x from both sides

Answer 7

oh hehe sorry

Answer 8

than would it be f(x) = y + 3

Answer 9

no

so in this way

x-x -y = 3 - x

make the calcule pls

Answer 10

x-x = 0

-y = 3 - x

but you need have on the left side +y so in this way you need multiplie both sides by -1 and will get

(-y)(-1) = (-1)(3 - x)

y = -3 +x or correct wrote

y = x - 3 so

f(x) = x - 3

hope helped understandably easy
