The cost c, in dollars, for bananas depends on the weight w, in pounds, of the bananas. this situation is represented by the function rule c=0.5w (graph each function rule. tell whether the graph is continuous or discrete)

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.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
