Question

Please help if you could

Consider the function represented by the equation y-6x-9=0. Which answer shows the equation written in function notation with x as the independent variable?

Answer 1

f(x)= 6x+9....

Explanation:

The given equation is:

y-6x-9=0

Add 6x+9 at both sides:

y-6x-9+6x+9=0+6x+9

Solve the like terms:

on the L.H.S -6x will be cancelled out by +6x and -9 will be cancelled out by +9

y=6x+9

Now convert it in function notation:

f(x)=y

f(x)= 6x+9....
