130 degrees!That should be your answer. :) Hope i helped
Given figures along the curve of C are: 10, 20, 30, 40, 50
∫c Nabla f * dr ⇒ f(B)−f(A)= 50 − 10 = 40
<span>To find the range of this function, simply plug each of the end values into the original equation. In this case, with x of -2, the function becomes f(x) = 6+1 or 7, and with x of 7, the function becomes f(x) = -21+1 or -20. As such, the range of the function is -21 <= f(x) <= 7.</span>
