The absolute value equation is true for x ≥ 0 and the negative values of x in the solution set would not work
The absolute value equation
The equation is given as:
|x| = x
The parent function of an absolute value equation is
f(x) = |x|
When f(x) = x and f(x) = x, it means that the absolute value equation is true from values of x greater than or equal to 0 i.e. x ≥ 0
Why the numbers in the solution set do not work?
In (a), we have:
x ≥ 0 --- the domain
This means that negative values of x in the solution set would not work
