f(x)=|-34x-1|

Combine x and 34.

f(x)=|-x⋅34-1|

Move 3 to the left of x.

f(x)=|-3×4-1|

f(x)=|-3×4-1|

Subtract f(x) from both sides of the equation.

0=|-3×4-1|-f(x)

Rewrite the equation as |-3×4-1|-f(x)=0.

|-3×4-1|-f(x)=0

The given equation |-3×4-1|-f(x)=0 can not be written as y=kx2, so y doesn’t vary directly with x2.

y doesn’t vary directly with x
