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)? (3 points) part b: write any two solutions for f(x). (3 points) part c: what is the solution to the equation p(x) = g(x)? justify your answer. (4 points)
