In a certain function, an output is 4 more than half its input.
patriot [66]

Answer:

x          y

-10      -1

0         4

4          6

6          8

Step-by-step 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= \frac{1}{2} x + 4

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

x = -10 , y= \frac{1}{2}(-10) + 4=-5+4 = -1

x = 0 , y= \frac{1}{2}(0) + 4=0+4 = 4

x = 4 , y= \frac{1}{2}(4) + 4=2+4 = 6

x = 8, y= \frac{1}{2}(8) + 4=4+4 = 8
