The lengths of a particular type of metal rod are modeled by the equation r = |–24x + 120|, where r represents the lengths of the rod in inches, and x represents the speed at which the rods are produced, in rods per minute. if the manufacturing process is too fast or too slow, the rods will not be long enough. at what speeds will the lengths of the rods be greater than 48 inches?
a. the length of the rods will be greater than 48 inches when x > 3 or x < 7 rods per minute.
b. the length of the rods will be greater than 48 inches when x < 3 or x > 7 rods per minute.
c. the length of the rods will be greater than 48 inches when x > –3 or x < –7 rods per minute.
d. the length of the rods will be greater than 48 inches when 3 < x < 7 rods per minute

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.
