15 Questions
What is a predefined function in algebra?
A predefined function in algebra is defined as a rule or correspondence between values, called the function’s arguments, and the unique value of the function associated with the arguments.
What does the function f(x) = 2x + 5 represent?
The function f(x) = 2x + 5 represents a rule or correspondence where the value of the function is equal to two times the input plus five.
What does the pow(x, y) function do?
The pow(x, y) function calculates the value of x raised to the power of y.
What does the floor(x) function do?
The floor(x) function calculates the largest whole number not greater than x.
Why do we need functions in programming?
Functions facilitate the creation of programs by enabling developers to divide a problem and code into smaller, more manageable parts.
The function f(x) = 2x + 5 returns the value 9 when x = 2.
True
The sqrt(x) function can calculate the square root of a negative number.
False
The floor(48.79) function returns 49.0.
False
The pow(x, y) function can only accept double or float data types for both x and y.
False
A function declaration provides all the information about what the function does exactly.
False
What does the floor(x) function do?
Calculates the largest whole number not greater than x
What does the pow(x, y) function do?
Calculates xy
What does the sqrt(x) function do?
Calculates the nonnegative square root of x for x >= 0.0
What is the purpose of a function declaration in programming?
To provide all the information about what the function does exactly
Why are functions important in programming?
To divide a problem (and also a code) into smaller parts
This quiz covers the concept of functions in programming, specifically focusing on the definition of a function, different types (returning value and void), and its identification by name. It also discusses how functions allow for the division of complex programs into manageable pieces.
