Agroup of volunteers plant trees at a community park every summer. the graph shows the number of trees in the park each year since they began planting trees. what is the unit rate?
25 trees per year
50 trees per year
75 trees per year
100 trees per year

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.
