10) Interpret the following correlations, including the strength and direction of the variables. For example if the number is +0.5 correlation between hair color and height, you would need to specify how strong the relationship between the two variables is and that as one increases the other does too​

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.
