Need help on this certain question

As x increases , y decreases then increases

Step-by-step explanation:

There are two situation

1> when x < 0

2> when x>= 0

let see

when x < 0

we see that as value of x moves from -ve value towards zero (i.e x is increasing) then value of y is decreasing( value of x has moved from positive side of y( above x-axis) towards negative side of (below x-axis)\

Thus, we can say that

for x < 0

As x increases , y decreases

when x>= 0

we see that as value of x moves from 0  towards +ve  value(i.e x is increasing) then value of y is increasing( value of x has moved from negative side of y( below x-axis) towards positive side of (above x-axis)\

Thus, we can say that

for x >= 0

As x increases , y increases

combining both observation it can be said that

As x increases , y decreases then increases which is equal to fouth option

51

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
