The graph shows the functions f(x), p(x), and g(x):
Graph of function g of x is y is equal to 1.8 to the power of x. The straight line f of x joins ordered pairs 6, 2 and 2, minus 2 and is extended on both sides. The straight line p of x joins the ordered pairs 3, 6 and 6, 2 and is extended on both sides.
Part A: What is the solution to the pair of equations represented by p(x) and f(x)?
Part B: Write any two solutions for f(x).
Part C: What is the solution to the equation p(x) = g(x)? Justify your answer.
