Question

Consider the function represented by the equation y – x – 4 = 0. What is the equation written in function notation, with x as the independent variable?

Answer 1

Well, in slope-intercept form, the equation will be y = x + 4. In standard form, the equation will be x - y = -4.

Answer 2

Answer:

$y = x+4$

Step-by-step explanation:

Given : The function represented by the equation $y - x- 4 = 0$

To Find: What is the equation written in function notation, with x as the independent variable?

Solution:

$y - x- 4 = 0$

$\Rightarrow y- x = 4$

$\Rightarrow y = x+4$

Now y depends on x

So, x is an independent variable.

Hence  the equation written in function notation, with x as the independent variable is $y = x+4$
