Please hurry, will mark brainliest if you answer correctly

The answer is 0

Step-by-step explanation:

The order of the operations is:

So first multiply and after divide and sum this result to 7 for substract to -12.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

think about it deeply and passionately about this property

i am sorry
