What are two important factors to remember when writing ratios correctly?

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

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
