. Consider the function named changeRed that creates a rectangular image of width 256 showing all the changes of the color red, from left to right repeatedly, while blue and green are both set to 0. With height set to 200, the resulting image is shown here. The function changeRed has two parameters named width and height for the width and height of the rectangle. This function should start at the first pixel with red set to 0 and increment red by 1 with each new pixel it processes. After the red reaches 255, it should be reset back to 0 for the next row. This function returns the newly created image. The function header is shown below. function changeRed(width, height) { Now consider allowing different values of blue and green. For example, if blue was 200 and green was 100, then as red changed from 0 to 255 the resulting image would change from a green color to an orange color as shown here: Which of the following best describes how to modify the changeRed function so that different values of blue and green could easily be used when the function is called? Add two parameters, one for the blue color and one for the green color. Then in the code set blue to be the blue number passed in and green to be the green number passed in. In the function just change the values of blue and green to the desired values. Change it from a function to just code and copy the code for each value of blue and green you want to use. Add three parameters, one for the blue color, one for the green color and one for the red color. Then in the code set blue to be the blue number passed in, green to be the green number passed in and red to be the red number passed in.
