Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x

If square root x = -7, then x= -49 true or false

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.
