Find an exponential function that passes through the points (−2,6)(−2,6) and (2,1)(2,1). Solution Because we don’t have the initial value, we substitute both points into an equation of the form f(x)=abxf(x)=abx, and then solve the system for a and b. Subst...

Range of an exponential function is y > 0. Range oflogarithmic functionis ℝ. To find the range of a rational function y = f(x), solve it for x and set the denominator ≠ 0. How to Find Range of a Function? If a function is present in one of the functions mentioned in the ab...
Determine the degree of the polynomials in the numerator and denominator. The degree of a polynomial is equal to its highest exponential value. In the example equation, the degree of the numerator (x – 2) is 1 and the degree of the denominator (x^2 – x – 2) is 2. ...
