Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Choose 0 to substitute in for x to find the ordered pair.
Replace the variable x with 0 in the expression.
f(0)=6-(0)3
Simplify the result.
Cancel the common factor of 6-(0) and 3.
Rewrite 6 as -1(-6).
f(0)=-1⋅-6-(0)3

f(0)=3(-1(-2+0))3
Cancel the common factors.
Factor 3 out of 3.
f(0)=3(-1(-2+0))3(1)
Cancel the common factor.
f(0)=3(-1(-2+0))3⋅1
Rewrite the expression.
f(0)=-1(-2+0)1
Divide -1(-2+0) by 1.
f(0)=-1(-2+0)
f(0)=-1(-2+0)
f(0)=-1(-2+0)
Simplify the expression.
Rewrite -1(-2+0) as -(-2+0).
f(0)=-(-2+0)
Add -2 and 0.
f(0)=2
Multiply -1 by -2.
f(0)=2
f(0)=2
The final answer is 2.
