Question

Write the equation in a function format.x + 4y = -12

Answer 1

Given the equation:

x + 4y = -12

To write this equation ain function format take the following steps:

• Step 1

Rewrite the equation in terms of y:

x + 4y = -12

4y = -x - 12

Divide through by 4:

`\begin{gathered} (4y)/(4)=(-x)/(4)-(12)/(4) \\ \\ y\text{ = -}(1)/(4)x-3 \end{gathered}`

• Step 2:

Replace the y, with f(x)

`f(x)=-(1)/(4)x-3`

This means that the function depends on x.

f(x) is the output depends on the input x.

Therefore, the equation in function format is:

`f(x)=-(1)/(4)x-3`

ANSWER:

`f(x)=-(1)/(4)x-3`
