The frequency of a sinusoidal graph is the number of cycles it completes in the interval 0 to 2π radians.

From the given sinusoidal graph it is noticed that the the graph complete its one cycle in the interval 0 to \frac{\pi}{2}.

If the complete its one cycle in \frac{\pi}{2}, then the number of cycles completed by the graph in the inteval 0 to 2π is

The cost for x number of gallons of heating oil can be represented by the function f(x)=4x+6 in the context of the problem expla
deff fn [24]

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.
