Learn how to evaluate a function for a given value

The video tutorial explains the concept of functions in mathematics, focusing on the relationship between input and output values. It demonstrates how to calculate the output of a function by substituting a given input value into the function's rule. The example used involves calculating the output for an input value of 4 in the function F(x) = 17x + 3, resulting in an output of 71. The tutorial also covers how to express the input-output relationship as a coordinate point, concluding with a brief clarification session.

Calculate the output when the input value is X = 4 using the function provided.
