Applying iram to a table of values

The video tutorial explains discrete functions and their properties, focusing on the left hand sum method for approximation. It highlights the differences in intervals and provides a calculation example to demonstrate the method.

What is a key characteristic of a discrete function?

• It is always linear.

• It lacks values between certain points.

• It can be easily integrated.

• It has continuous values.

Why can't we find the integral of a discrete function in the traditional sense?

• Because it is always zero.

• Because it is always negative.

• Because it is too complex.

• Because it lacks a continuous function to integrate.

What is the purpose of the Left Hand Rectangular Approximation Method?

• To calculate the derivative of a function.

• To solve linear equations.

• To approximate the area under a curve using discrete data.

• To find the exact value of an integral.

In the Left Hand Rectangular Approximation Method, what do the rectangles represent?

• The slope of the tangent line.

• An approximation of the area under the curve.

• The difference between two functions.

• The exact area under the curve.

What is the width of the interval from 2 to 5 in the example calculation?

• 3

• 2

• 4

• 1
