Tutorial Exercise Use Part 1 of the Fundamental Theorem of Calculus to find the derivative of the function. 73 +4 Step 1 By the Fundamental Theorem of Calculus Part 1, we know that if g(x) = / "f(t) at, then O g' ( x) = f'(x ). O g' ( x ) = 0. O g' (x) = f( x). O g' ( x ) = F ( x ) . O g' ( x ) = a. Step 2 Let f (t ) = -and g(x ) = / 73 + 4 2 Then by FTC1, we know that g'(x) = f(x) = 3 +4 X Submit Skip (you cannot come back) Need Help? Read It
