What is the frequency of the sinusoidal graph?

Alright, lets get started.

For finding frequency, we need to first find the period of the graph.

The period of a sinusoidal graph is the time interval in which it repates its pattern.

In the graph, we can see, after time, it repeats its pattern.

Hence the period of the graph is .

Now we need to find its frequency.

The formula for frequency is :

This is the

Hope it will help :)

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

do you confirm there was a mistake in the question?

the answer is ! ?
