If f (x)= |x+8| , find f (-11) (points: 1) A. -3 B. 3 C. -19 D. 19 Help? Please? :)

OpenStudy (adamaero):

just plug -11 in for x what do you get?

OpenStudy (adamaero):

|these bars| mean absolute value of that number

OpenStudy (anonymous):

f(x) = | x + 8| f(-11) = | -11 + 8 | f(-11) = |-3| since || means absolute value it is f(-11) = 3 so B
