2. a. Consider the following functions, f(x) and g(x):

f(x) = 2x - 1 and g(x) = 4 - 2x - x2.

Use Excel to create a single graph of both functions for x in the interval [-6, 4]. Label your graph clearly with the domain adjusted to the given interval.

b. Find the x and y-intercepts for both functions. Give the slope of the line and the vertex of the parabola. Find all points of intersection between the curves. Write this information in a clear paragraph. If your answer uses the quadratic formula and has a square root, then give both the decimal answer to four significant figures and the answer including the square root. (You may need to use Equation Editor to write the second form of your answer.)
