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
