Question

In a certain function, an output is 4 more than half its input.

Complete the input/output table for the function.

Answer 1

x y

-10 -1

0 4

4 6

6 8

Explanation:

an output is 4 more than half its input.

Input of a function is x and the output of a function is y

output y is 4 + half of input x

`y= (1)/(2) x + 4`

Now we complete the below table, plug in the value of x and find out y

x = -10 ,
`y= (1)/(2)(-10) + 4=-5+4 = -1`

x = 0 ,
`y= (1)/(2)(0) + 4=0+4 = 4`

x = 4 ,
`y= (1)/(2)(4) + 4=2+4 = 6`

x = 8,
`y= (1)/(2)(8) + 4=4+4 = 8`
