The absolute value function is written f(x) = |x|. it is composed of the lines y = x and y = -x. its domain is the real numbers and its range is the set of real numbers: [0, ∞). its graph is: 1. the absolute value function is y = |x|. is it possible for the absolute value function to ever have a negative y value? here is a ’m looking for the actual definition of the absolute value in terms of distance with a detailed example to support your response. is there a way to transform an absolute value function to have negative outputs? 2. define the absolute value function, y = |x|, as a piecewise function. include complete sentences and examples to justify your answer to receive credit.

1.
no, there will never be a negative y-value.  y= |x| will always be nonnegative. |x| can be distance x is from 0 and a distance can never be negative.

2.
you can define it as
y = |x| = x if x ≥ 0, -x if x < 0

absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"

example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does

if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.

for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does
