Question

Which tables contain correct pairs of input and output values for the function ? Select all the correct answers.

Answer 1

domain (0,1,3,5,6) range (-20,-16,-8,0,4) function f(x)=4-4x

domain (-2,-1,0,3,4) range -13,-8,-3,12,17) function f(x)=5x-3

domain (-4,-3,0,2,4) range (-40,-20,0,20,40) function f(x)=10x

domain (-3,-2,-1,2,6) range (0.5,0,-1.5,3,2) function f(x)=3/x+1.5

Answer 2

The correct answer for the question that is being presented above is this one: "A rule is a function if each element in the domain goes to exactly one element in the range."

The following tables that contain correct pairs of input and output values for the function are the:
(1)
Input (x) -1.6 0.4 2.2 3.7
Output f(x) -5.5 2.5 6.75 10.75

(2)
Input (x) 1.1 2.4 5.3 6.9
Output f(x) 4.25 7.5 11.75 17.25
