What are the benefits of writing functions that use parameters and return List 2 please and explain what is return

Ratling [72]

Answer and explanation:

There are many benefits of writing functions that use parameters and return. Some of them are:

1. Flexibility: With functions having parameters, several values of the parameters can be used at invocation time thereby making the application flexible. For example, given the following function in Java.

public void showName(String name){

System.out.println("Your name is " + name);

}

To call this method (function), the programmer could use various values for the name parameter used in the function like so:

showName("John");

showName("Doe");

If the function didn't have a parameter, it is possible it will only print a hardcoded name every time the function is called.

2. Scope Control: When a function is allowed to return a value, it helps to work around scope issues since variables declared within a function are limited to that function and do not exist outside the function. This means that the values of these variables cannot be used anywhere else outside the function in which they are being declared. However, if the function returns a value, the value can be used anywhere else in the program.

For example:

public String getDouble(int x){

int y = x * 2

return y;

}

The function above returns twice the value of the argument supplied to it. Since the integer variable y is declared within the function, it's value cannot be used outside the function. However, since the value is being returned by the function, it could be used anywhere the function is being called. Thanks to the return keyword.

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)

alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

$\dfrac{y-0}{x-4} = -4$

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)
