Write the equation, of the trigonometric graph! help please asap

Look again at the equation y = a sin (bx + c). Notice that we have varied a, the amplitude, and b, the period. ... In the first equation, y = sin x, c is equal to zero. Look at the graph on the left to see that curve as well as the curve of the equation y = sin (x + 2).

Step-by-step explanation:

except a rational number. : )

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
