If a ball is thrown upward at 64 feet per second from the top of a building that is 120 feet high, the height of the ball is given by s = 120 + 64t − 16t2 feet where t is the number of seconds after the ball is thrown. how long after it is thrown is the height 120 feet?

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.
