What the is the answer to this i can't get it to graph on my calculator

B

Step-by-step explanation:

Taking an algebraic approach

If f(x) = f(- x) then f(x) is Even

If(- x) = - f(x) then f(x) is Odd

f(- x) = + 12 - 14 + 13

       = + 12 - 14 + 13

Since f(x) = f(- x) then f(x) is Even → B

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
