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?yesno 2)  Is (0, 4) a solution of y = 5x + 4?yesno 3)  Is (2, 3) a solution of y = 3x - 4?yesno 4) Determine if each relation below represents a function.  Does each input have only one output?x   y1   32   43   54   6 yesno List the range (output) for the following function.x   y1   32   43   54   6{1, 2, 3, 4}{3, 4, 5, 6} List the domain (input) for the following function.x   y1   32   43   54   6{1, 2, 3, 4}{3, 4, 5, 6} 5) Determine if each relation below represents a function.x   y1   32   33   34   3 yesno List the domain for the following function.x   y1   32   33   34   3{1, 2, 3, 4}{3} List the range for the following function.x   y1   32   33   34   3{1, 2, 3, 4}{3} 6) Determine if each relation below represents a function.x   y1   32   43   53   6 yesno 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. 1, 3, 6,      , 15, 21... 11)  Find the missing term. 2, 7, 12,    , 22, 27,... 12)  Find the missing term. 1, 4, 9, 16,     , 36, ...   Which graph corresponds to the situation? Gracie walked along the canal, stopped for a picnic, then walked back to her car.Graph 1Graph 2Graph 3 Which graph corresponds to the situation? Alexis walked along the canal, stopped for a picnic, andthen continued to the end of the trail.Graph 1Graph 2Graph 3 Which graph corresponds to the situation? Evan floated down the canal and then waited for his ride home.Graph 1Graph 2Graph 3 15)  Is this data continuous or discrete?continuousdiscrete 16)  Is this data continuous or discrete?continuousdiscrete 17)  Is this data increasing, decreasing, both, or neither.increasingdecreasingbothneither 18)  Is this data increasing, decreasing, both, or neither.increasingdecreasingbothneither 19)  Is this data linear or non-linear.linearnon-linear 20)  Is this data linear or non-linear.linearnon-linear
