Thanks so much!

f (∛( -8) ) + f (- pi) + f (√50 ) + f(9/2)

Edit

Sorry... I didn't see the absolute bars in the first function....so ....the answer is

l-2 l + (-3)^2 + (8)^2 + l 4 l =

2 + 9 + 64 + 4 =

79

Is there another way to do this? Apparently 75 isn't correct :/

Oh it would be positive 2 so 79 :D
