Answer:
(x) =
Step-by-step explanation:
let d(x) = y and rearrange making x the subject, that is
2x - 4 = y ( add 4 to both sides )
2x = y + 4 ( divide both sides by 2 )
x =
Change y back into terms of x, so
(x ) =
Q #3. Ifetify the mapping diagram that represents the relation and determine whether the relation is function..{(- 3,-6),(-1,-6)
,(5,-6),(8,-6)
1 answer:
Every ordered pair has a second number of -6, so the mapping with -6 as the sole number on the right is the appropriate mapping. A mapping is only <em>not a function</em> if it maps a number to two or more different values (as shown in the top diagram of your attachment).
The appropriate choice is not shown in your question. It would be the one attached below.
