We know about functions where exponents are raised to different variables, to produce quadratics, cubics, quartics, and so forth. But what about when the variable itself is an exponent? This is called an exponential function, and they are important for modeling things like population growth and other real-world scenarios. Let's learn about them ...

👉 Learn how to evaluate the limit of a function from the graph of the function. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. When evaluating the limit of a function from the graph of the function we observe where the y-value of the graph ...

This video explains how to evaluate a definite integral given the graph of a function and the area bounded by the function and the x-axis. The function is above and below the x-axis. Site: http://mathispower4u

Function Notation is an easy way to display the input of a function. The f(x) is f of x and displays the input of the function. The f(x) is f of x and not f times x f is used most often but any letter can be used. When you evaluate a function you simply plug in the value for x into the output. For example, Evaluate f(x) = 2x + 5 If x =5 then ...

For the following exercises, use graphs of f(x), shown in Figure 6, g(x), shown in Figure 7, and h(x), shown in Figure 8, to evaluate the expressions. g(f(1)) g(f(2)) f(g(4)) f(g(1)) Here are all of our Math Playlists: Functions: 📕Functions and Function Notation: https://www.youtube.com/playlist?list=PL_3h4GvKc6GBBVJ78amQA_efjscbZvwr0 📗 ...
