Nate's classroom has three tables of different lengths one has a length of 4 1/2 feet another has a length of 4 feet the third has a length of 2 1/2 feet what is the length of all three tables when pushed in the end

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.

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)
