No this is not a function because a function can only have one output for each input.

It does not because for each y value there should only be one x value

Step-by-step explanation:

Simply replace X with 3 etc...

f (x) = 4x + 7

f (3) = 4 (3) + 7

f (3) = 12 + 7

f (3) = 19

f (2x) = 4 (2x) + 7

f (2x) = 8x + 7

What is the answer to this question

umka21 [38]

First you bring the 9 over with the seven
$-2= \sqrt[3]{x+9}$
Now cube both sides
$-8=x+9$
Finally subtract 9 over and get
$x=-17$

Check
$7=9+ \sqrt[3]{-17+9}$
$7=9+ \sqrt[3]{-8}$
$7=9+(-2)$
7=7
