F1 Intro to Functions Practice Quiz

The range is a list of all possible outputs. The outputs areusually represented by "y", are usually the dependentevent, and are usually the effect. The domain is a list of all possible inputs. The inputs areusually represented by "x", are usually the independentevent, and are usually the cause. 1) Is (2, 14) a solution of y = 5x + 4? Replace x with 2 and y with 14 and see if it is true. y = 5x + 4 becomes 4 = 5(2) + 4. Is it true? yes no 2) Is (0, 4) a solution of y = 5x + 4? yes no 3) Is (2, 3) a solution of y = 3x - 4? yes no 4) Determine if each relation below represents a function. Does each input have only one output? x y 1 3 2 4 3 5 4 6 yes no List the range (output) for the following function. x y 1 3 2 4 3 5 4 6 {1, 2, 3, 4} {3, 4, 5, 6} List the domain (input) for the following function. x y 1 3 2 4 3 5 4 6 {1, 2, 3, 4} {3, 4, 5, 6} 5) Determine if each relation below represents a function. x y 1 3 2 3 3 3 4 3 yes no List the domain for the following function. x y 1 3 2 3 3 3 4 3 {1, 2, 3, 4} {3} List the range for the following function. x y 1 3 2 3 3 3 4 3 {1, 2, 3, 4} {3} 6) Determine if each relation below represents a function. x y 1 3 2 4 3 5 3 6 yes no 7) Complete the table for y = 3(x + 1). x y -1 0 1 2 8) Complete the table for y = 3x - 5. x y -1 0 1 2 9) Complete the table for y = -x - 7. x y -1 0 1 2 10) Find the missing term.
