Point A is launched horizontally away from a wall and a ( t ) represents Point A's distance from the wall (in meters) in terms of the number of seconds t since the point was launched. Point B is also launched from the wall, but travels 1.5 times as fast as Point A. Suppose b(t) represents Point B's distance from the wall (in meters) in terms of the number of seconds t since the points were launched. Write a function formula for b using the function a. a. b(t)=1.5a(t) Correct The graph of function a is shown below (in black). Sketch the graph of function b.
