Answer:
Step-by-step explanation:
A function maps an x-value to a single y-value. The graph of the parabola on the left does that.
The table on the right maps -1 to both 10 and 20, so does not meet the definition of a function.

let's evaluate ~

![\qquad \sf \dashrightarrow \: - 6 - [(5 \cdot6x) - (5 \cdot4)]](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3A%20-%206%20-%20%5B%285%20%5Ccdot6x%29%20-%20%285%20%5Ccdot4%29%5D)



I hope you understood the whole procedure ~
Mean = (20 + 14 + 29 + 39 + 33 + 25 + 19 + 35)/8 = 214/8 = 26.75
Range = highest number - smallest number = 39 - 14 = 25
Answer:
d = 26
