Least common multiples are most helpful foR

For which rational expression is -2 an excluded value of x?

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

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.
