We know that for a s b s c, ( Fox) dx + ( " R(x ) dx = ("F(x ) dx . Using the first and second integrals, since we have -45154, 4 0 4 [ 1( x ) ax + ( "F( x ) dx = / f ( x ) dx . -4 1-4 Step 2 We also know that / f(x) dx = -/ f(x) dx. Therefore, we can say the following. -4 -4 f ( x ) dx -2 0 -2 Step 3 Using these results, we can say the following. X f(x ) dx X Submit Skip (you cannot come back)
