Question

Consider the function represented by 9x + 3y=12 with x as the independent variable. How can this function be written using function notation?

Answer 1

Answer: f(x)=−3x+4

Explanation:

In a function

y

=

f

(

x

)

,

x

is the independent variable and

y

is the dependent variable.

So to represent the given equation as a function, it is just enough to solve it for y
