Homework Statement
Given f(x)= square root of x - 4, write the equation for -f(x) and f(-x).
Sketch the three graphs on the same set of axes
Determine any points that are invariant for each reflection
The Attempt at a Solution
well basically I did the first part of the question and the result i got was
-f(x) = -square root of X + 4
f(-x) = square root of -x -4
the second part where it asks to graph these 3 equations, I've graphed the f(x) equation and the -f(x) equation but I can't graph the f(-x) equation. Simply because i get an error when i try to square root a negative number. So how would i graph this kind of eqation?
