Answer:
y=|x|
Step-by-step explanation:
We know
general modulus function passes through origin as |0| is 0
And it's symmetric on both sides of y axis .
As it's not one -one function
Means
So the graph is y=|x|
The only one is 40 6 12 18 24,30,36,42
We can create a formula first.
X will be the unknown number
840= 357+x
-357 -357
483 = x
Hope this helps
