Question

(Functions)
Find f(-5) and f(2) for the given function.
f(x)=|x-1|
I forgot how to do it.. can someone explain please?

Answer 1

Have you considered substituting?

f(x) = |x-1|
f(3) = |3-1|
f(12) = |12-1|
\(f(\sqrt{\pi}) = |\sqrt{\pi}-1|\)
f(Plastic) = |Plastic-1|

Answer 2

what is the absolute value of a number?

Answer 3

|3| = 3
|-3| = 3
