In this lesson, I'll show you how to find the y-intercept of an exponential function -- which is really not as bad as it sounds & you probably already know how to do it!

Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

QUESTION: The points (0,20) and (3,1280) represent values of an exponential function of the form y = a(b)x. Find the values of a and b, and express a function passing through these points. SOLUTION: …

Mar 14, 2024 · To determine the y-intercept of an exponential function, simply substitute zero for the x-value in the function. The reason this works is because all points on the y-axis have an x-value equal …

In conclusion, to find the y-intercept of any exponential function, remember this simple process: plug x = 0 into the function. The resulting value of y will be the y-intercept, which is a key starting point for …

Mar 24, 2017 · For example, let's consider the exponential function y = 2^x. To find the y-intercept, we set x = 0 and evaluate the function: y = 2^0 = 1 Therefore, the y-intercept of the given exponential …

Graphing and sketching exponential functions: step by step tutorial. The properties such as domain, range, horizontal asymptotes and intercepts of the graphs of these functions are also examined in …

Now that we know how to pull out the pieces of an exponential function when we give you the formula, let’s go backwards: write the formula based on the pieces that we give you.

Sometimes we are given information about an exponential function without knowing the function explicitly. We must use the information to first write the form of the function, then determine the …
