Pls help me!! 1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.

2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).

3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.

Enter your answer in the form "y = …".

4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).

(Assume grid lines are spaced 1 unit apart.)

5. In the third picture is a portion of the graph of a function, y=u(x):

What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
