The graphing calculator window shows the graph of a function f(x) and is derivatve function r'(x). Decide which is the graph of the function and which is the grach of the dervative.Which of the following methods would be helptul in distinguishing the graph of the function from the graph of its derivative?A. Calculate (or roughly guess) the amount of area between each line and the horizontal axis and identity the line with the largest area.B. Calculate (or roughly guess) the amount of area under each line and identify the line wth the largest area.C. Compare the y-intercepts of each line to see if a horizontal tangent line occurs at that y-value on the other line.D. Compare the x-infercepts of each line to see if a horizontal tangent line occurs at that x value on the other line.Choose the graph that is the function and the graph that is the derivative.A.Y1 is the graph of the function.Y2 is the graph of the dervativeB.Y2 is the graph of the function. Y1 is the graph of the derivative.
