So i need to set number 4
to equal 0
so how would that look
would it be like
2m^2+9m+7-3=0
? ?

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.

step-by-step explanation:

c

step-by-step explanation:

i think because what else can be a sample of every member

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
