What is the first step in inverse of functions?

• Find the derivative of the function
• Swap the x and y coordinates
• Graph the function

What is composition of functions?

• It is the process of combining two functions by applying one function to the output of another
• It is the process of dividing two functions
• It is the process of subtracting two functions
• It is the process of multiplying two functions

If you saw f(g(x)), which function would be written first?

• Function g
• Function f
• Both are written at the same time
• None of the above

If you saw f(g(x)), which function would be composed inside the original function?

• Function f
• Function g
• Function x
• None of the above

What is the inverse operation of squaring something?

• Square root
• Multiplication
• Division
• Subtraction

• It represents the composition of the functions f and g, evaluated at x
• It represents the multiplication of the functions f and g, evaluated at x
• It represents the division of the functions f and g, evaluated at x
• It represents the subtraction of the functions f and g, evaluated at x

Graph the inverse of (2,3)

What is the inverse operation of taking the cube root of something?

• Cubing

• Square root

• Multiplication

• Division

What is the result of the composition of function f(x) = x + 2 and g(x) = 2x?

• f(g(x)) = 2x + 2

• f(g(x)) = x + 4

• f(g(x)) = 4x + 2

• f(g(x)) = 2x^2 + 2

What does one-to-one relation mean?

• Each element of one set is related to one element of another set
• Each element of one set is related to multiple elements of another set
• Each element of one set is not related to any element of another set
• Each element of one set is related to all elements of another set
