Now, we can plot these points and connect them with a straight line to have the graph of f(x).
Graph of h(x)
Let's recall the definition of a reflection in the y-axis.
Changing the sign of a function's input reflects the original function in the y-axis.
Original Function & Reflected Function
y=f(x) & y=f( -x)
Because we have h=f( -x), we can state that h is a reflection in the y-axis of f. To graph h, let's make a table of values taking some inputs from f and change their signs.
