Answer:
f of x = 6 x + 9
Step-by-step explanation:
Given the equation :
y minus 6 x minus 9 = 0
y - 6x - 9 = 0
Write the equation in function notation with x as the independent variable.
y - 6x - 9 = 0
Make y the subject of the formula;
Move - 6x - 9 to the Right hand side
y = 6x + 9 (sign changes)
Expressing y as a function of x;
f(x) will be equal to y ;
Mathematically ;
f(x) = y
Hence ;
f(x) = 6x + 9
From the general linear equation :
mx + c = 6x + c
x = independent variable
