please do this will give you a food review this is due in this morning thanks

Activity A: Get the Gizmo ready: Adding two On the ADDING tab, turn off Show sum and functions Show probe. Click the button to reset the graph. 1. In the Gizmo, graph f(x) = x2 - x + 2 and g(x) = x? - 4x + 1. Both of these are quadratic functions (degree 2) whose graphs are parabolas. A. Add the like terms in the polynomials x2 - x + 2 and x2 - 4x + 1 to find the sum of the functions. Fill in the blank belgiv to write the function that represents the sum. (f + g)(x) =. Select Show sum to check your answer. Notice that the sum is the equation of the red parabola shown in the Gizmo. B. Evaluate f(x), g(x), and (f + 9)(x) when x = -1. Show your work below. Then select Show probe and drag the probe to x = -1 to check your answers. (You can click on the graph and drag down to see the point where the probe intersects (f + g)(x).) C. When x = -1, how is f(x) + g(x) related to (f + g)(x)? 2. Turn off Show sum and Show probe. Graph f(x) = 2x2 + 4x + 3 and g(x) = -2x2 - 3x + 2. A. What is the sum of the functions? (f + 9)(x) = Select Show sum to check your answer. B. Select Show probe. Drag the probe and study the y-values of the functions at different x-values. At any given x-value, how is f(x) + 9(x) related to (f + g)(x)? C. Experiment with more functions. At any given x-value, how is f(x) + g(x) related to (f + g)(x)? 3. If (2, 1) lies on the graph of function fand (2, 5) lies on the graph of function g, what point must lie on the graph of f+ g? (
