During a nature walk Jill identified 20 species of animals and plants she said that 1/3 of the species she identified were animals can this be correct?

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.

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
