The output of a function is 10 more than 4 times the input. Find the input when the output is - 26?

- 9

Step-by-step explanation:

let x be the input value, then the function is

y = 4x + 10 ← equate to - 26

4x + 10 = - 26 (subtract 10 from both sides)

4x = - 36 (divide both sides by 4)

x = - 9

Thus the input is x = - 9
