step 1: start the debugger and set a breakpoint on the line containing the function.
step 2: step through the program and watch the value of x as it changes.
step 3: notice that the value of x^2 increases as x increases.
step 4: notice that 3 is added to the output of the function, no matter what value x is.
step 5: the function can now be expressed as: f(x)=x^2+3.
