Why is this the correct graph for the function y= x^2 -16 / x+4 explain !

Hi!

To better understand, we need to factorize the function. That is,

In a 1st degree function the linear coefficient cuts the y-axis. in this case the 4.

Hope this helps, good studios!

the expected value of the random variable : 0, 1 and 2

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
