What is the rate of change in the following equation?
y= 3x-1

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.

What is the correlation coefficient between the variables? round to three decimal places. enter your answer in the box

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me
