Hence, the correct answer is option “A”.

Expert Solution & Answer
Check Mark

Explanation of Solution

Defining a function:

It is a technique which is used to perform the particular task when the function is called by user using its name. The function can be used multiple times by calling the function in JavaScript. So, the defined function can be reused in JavaScript code.

Explanation for incorrect options:

Create a script block:

In this option, creating a script is a block of code with “<script>” element. This block is used to write the set of code and the block is cannot be reused by the user.

Hence, the option “B” is wrong.

Define an “if” statement:

In this option, “if” statement is a conditional statement which is used to check the value of variable with its appropriate condition. If the condition returns true, then it displays the “true” block, otherwise it executes “false” block. So, it cannot be reused by user.

Hence, the option “C” is wrong.

Use an onclick event handler:

“Onclick” is an event handler which is processed when the user clicks on the event. It is a predefined technique and used for “click” event.

Hence, the option “D” is wrong.

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with three different lights, each of which can be turned on or off, projecting onto a glass screen: We can create eight different colors based on the absence (0) or presence (1) of light sources R,G and B: R G B Color 0 0 0 Black 0 0 1 Blue 0 1 0 Green 0 1 1 Cyan 1 0 0 Red 1 0 1 Magenta 1 1 1 0 Yellow 1 White 1 Each of these colors can be represented as a bit vector of length 3, and we can apply Boolean operations to them. a. The complement of a color is formed by turning off the lights that are on and turning on the lights that are off. What would be the complement of each of the eight colors listed above? b. Describe the effect of applying Boolean operations on the following colors: Λ 1. Red(100) ^ Magenta(101)= Blue(001) 2. Bue(001) | Green(010)= 3. Yellow(100) & Cyan(011)= 2.[30 pts] Perform the following…

Methods (Ch6) - Review 1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java. There are two methods, method #1 which calculates the square root for positive integers, and method #2, which calculates the square root of positive doubles (also works for integers). public class SquareRoot { public static void main(String[] args) { } // implement a loop of your choice here // Method that calculates the square root of integer variables public static double myRoot(int number) { double root; root=number/2; double root old; do { root old root; root (root_old+number/root_old)/2; } while (Math.abs(root_old-root)>1.8E-6); return root; } // Method that calculates the square root of double variables public static double myRoot(double number) { double root; root number/2; double root_old; do { root old root; root (root_old+number/root_old)/2; while (Math.abs (root_old-root)>1.0E-6); return root; } } Program-it-Yourself: In the main method, create a program that…
