a) We are to use the given system of linear equations to find the value of p and q
To find these values, we have to solve the system of linear equations simultaneously
We have this as follows;
To get the value of q, we simply make a substitution for the value of q in any of the initial equations
We have this as;
b) Using the values of p and q obtained, we are to write down the equation for the exponential function
We have this as follows;
c) Here, we want to write the equation of the horizontal asymptote to the graph of f(x)
Mathematically, the asymptote is that line in which the graph approaches but will not touch as it moves away from the origin of the plot
With respect to the given question, we have this as follows;
