Question

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)
Add 6x + 9 on both sides and then you convert in function rotation

Answer 2

f(x) = - 6x + 9

Explanation:

y - 6x - 9 = 0
y - y - 6x - 9 = 0 - y
-6x - 9 = -y
y = 6x + 9
f(x) = 6x + 9
