Two neon lights are turned one at the same time. one blinks every 4 seconds and the other blinks every 6 seconds. in 60 seconds, how many times will they blink together?

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
