Consider the following piecewise-defined function. -x+2x-6 if x 4 f(x) = if x > 6 Step 1 of 3: Evaluate this function at x = 7. Express your answer as an integer or simplified fraction. If the function is undefined at the given value, indicate "Undefined". Answer Ke Keyboard Sh Selecting a radio button will replace the entered answer value(s) with the radio button value.
