Answer:
This means that the cost of 2 heating oil gallons is 14.
Step-by-step explanation:
f(x) = 4x + 6 , where x is the number of heating oil gallons.
And f(x) = 4x + 6 is the equation for the cost of x gallons.
When the number of gallons are 2 then the cost is;
f(2) = 4(2) + 6 = 8 + 6 = 14
This means that the cost of 2 heating oil gallons is 14.
