Q. 1 - Calculus

Question

Use the graph of f to estimate the values of A(1), A(2), A(3) 

Step-by-Step Solution

Answer

The area of A(1) is zero

The area of A(2) is 2.5 sq. units

The area of A(3) is 8.5 sq. units

Step 1: Given information

We are given a figure 

Step 2: Give the areas using the gridlines

We first find the area A(1)

Now now grids in between A(1) Hence the area is zero

Now we find the area A(2)

The are 2 complete grids and a half grid 

Hence the area is approximately 2.5 sq. units

Now we find the area A(3)

The are 7 complete grids and 3 half grids covered in between

Hence the area is 8.5 sq.units
