A trigonometric function models the monthly rainfall of a city, which reaches a maximum monthly rainfall of 8 inches in the spring and fall and a minimum monthly rainfall of 0 inches in the summer and winter. If models the monthly rainfall t months from when the monthly rainfall started being recorded for the city, what is the domain of function r?

A) [8,∞]
B)(-∞,∞)
C)(0,∞)
D) [0,8]

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
