Question 3: How do you recognize when a system is inconsistent and what are the two things you must write when solve these systems? How do you recognize when a system is dependent and what are the two things you must write when solve these systems? Inverse functions are special types of functions. Functions must be one-to-one functions to have an inverse. Two special types of inverse functions in mathematics are Exponential and Logarithmic Functions. Question 4: How do we know if a function is one-to-one? What are the three steps to find the equation of the inverse? An exponential function is a function in which the unknown variable x is in the exponent (not the base). Where f (a) = 22 is a quadratic function, f (a) = 2 is an exponential function. One special application to exponential functions is Compond Interest. In the formula A = P(1+ ") , the values of P, r, and t are given as numbers in the problem where n is given as a key word in the
