Inverse of Linear Functions Practice

What is the inverse of y=3x+5?

• y = 3x - 5

• y = (-1/3)x + 5

• y = (1/3)x - (5/3)

• y = (1/3)x + 5

What is the inverse of y=(1/3)x+5?

• y = 3x - 15

• y = (-1/3)x + 5

• y = (-1/3)x - 5

• y = 3x + 5

What is the inverse of y=(5/2)x?

• y = (2/5)x

• y = (-5/2)x

• y = (-2/5)x

What is the inverse of y=6x-54?

• y =(1/6)x + 9

• y = (-1/6)x - 9

• y = (-1/6)x + 54

• y = -6x + 54

How are the domain and range of a function and its inverse related to each other?

• A function's inverse has the same domain and range as the original function

• A function's inverse has the same domain as the original function, but the range is different

• A function's inverse has the same range as the original function, but the domain is different

• A function's inverse has a domain that is the original function's range and a range that is the original function's domain

What is the inverse of the given coordinates: (1, 2) (3, 4) (5, 6)

• (2,1) (4,3) (6,5)

• (-1,-2) (-3,-4) (-5,-6)

• (-2,-1) (-4,-3) (-6,-5)

• (1,2) (3,4) (5,6)

How can you find the equation of a function's inverse?

• Replace values of x with -x and y with -y in the original equation

• Replace values of x with -y and y with -x in the original equation

• Replace values of x with y and y with x in the original equation

• DO ABSOLUTELY NOTHING! MATH IS JUST ONE BIG LIE

The inverse of a function can be determined by switching the x and y values of their coordinates.

• True

• False
