Evaluating Function Values and Forms

The video tutorial explains how to calculate the values of a quadratic function, f(x) = 3x^2 + 15x, for different x values. It demonstrates the process of plugging in x values into the function to find corresponding y values. The tutorial specifically focuses on finding the missing y value for x = 4 and completing the table with the value for x = 5.

What is the general form of the function discussed in the video?

• f(x) = 3x^2 - 15x

• f(x) = x^2 + 15x

• f(x) = 3x^2 + 15x

• f(x) = 3x + 15
