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


Sagot :

Answer:

f(x) = x – 3

Step-by-step explanation:

The equation that is written in function notation, with x as the independent variable is D. f(x) = x – 3

Calculations and Parameters

To write the equation as an independent variable, we simply need to isolate y.

The next step would be to subtract x from both sides:

-y = 3 - x

To eliminate the -ve sign in y, we would divide both sides by -1

y= -3+x

If we rearrange, the answer would be:

f(x) = x – 3
