Let g be a function that is defined for all x, x at 2, such that 9(3) = 4 and the derivative of g is . _x216 - g(x) x2 WithxaZ. 1. Find all values of x where the graph of g has a critical value. 2. For each critical value, state whether the graph of g has a local maximum, local minimum, or neither. You mustjustify your answers with a complete sentence. 3. On what intervals is the graph of g concave down? Justify your answer. 4. Write an equation for the tangent line to the graph of g at the point where x = 3. 5. Does this tangent line lie above or below the graph at this point? Justify your
