The value of the question mark in the function machine -2 ⇒ *? -3 ⇒ -18 is x = -3
How to determine the value of the question mark
From the question, we have the following parameters that can be used in our computation:
-2 ⇒ *? -3 ⇒ -18
Represent the question mark with a variable
So, we have
-2 ⇒ *x -3 ⇒ -18
This implies that
-2 * x * -3 = -18
So, we have
6x = -18
Divide both sides by 6
x = -3
Hence. the value of the question mark is x = -3
