Question

Make an input-output table for the function y = 2x + 4. Use x-values of 1, 2, 3, 4, and 5. Input, x 1 2. 3 4 5 Output, y5 Input, x 1 2 Output, y6 8 10 12 14 2 3 4 5 Input, x 1 Output, y6 36 76 156 Input, x 1 2 3 5 Output, y5 7 8

Answer 1

option B

Explanation:

Function: y = 2x + 4

let the inputs for x = 1, 2, 3, 4, 5

To get the outputs, we insert each of the inputs:

when x = 1

y = 2(1) + 4 = 2 + 4

y = 6

when x = 2

y = 2(2) + 4 = 4 + 4

y = 8

when x = 3

y = 2(3) + 4 = 6 + 4

y = 10

when x = 4

y = 2(4) + 4 = 8 + 4

y = 12

when x = 5

y = 2(5) + 4 = 10 + 4

y = 14

The output values are: 6, 8, 10, 12, 14

The input -output table for the function is option B
