I think there is an error in your typo for D. You mean -25 right?

anonymous · Answer

yes, sorry about that.

anonymous · Answer

D is -25, (not -2)

anonymous · Answer

Am I plugging -5 for x?

anonymous · Answer

Yup :)

anonymous · Answer

oh, so it would the n be 
f(-5)=-75 and the answer is E. Right?

anonymous · Answer

no , -25

anonymous · Answer

No you forgot to square it. negative times a negative is a positive

anonymous · Answer

b/c (-5)^2=25, my bad

anonymous · Answer

Okay, but there is an absolute value sign outside the equation

anonymous · Answer

D. is not your answer though

anonymous · Answer

and comparing to a previous function, where would this function be? like would it be shifted 5 units to some direction comparing to the f(x)?

anonymous · Answer

@x3pufflix3, why wouldn't D be not my answer?

anonymous · Answer

oh absolute value!

anonymous · Answer

it is B

anonymous · Answer

Because you have an absolute value sign. Hence the negative becomes a positive.

anonymous · Answer

The correct answer is 25 beause l-25 l become a POSITIVE 25

anonymous · Answer

b/c  I-25I=25
my bad! Sorry about that.
