Consider the function f(x) = p(0.5)' +9 where p and q are constants. The graph of f(x) passes through the points (0,6) and (1,4) and is shown below. a. Use the equations 6 = p + 9 4 = 0.5p + 9 to find the values of p and of q.b. Write down the equation of the exponential function b. Write down the equation of the horizontal asymptote to the graph of f(x).
