Problem 65 - College Algebra

Question

What does a \([-20,2,1]\) by \([-4,5,0.5]\) viewing rectangle mean?

Step-by-Step Solution

Answer

This viewing rectangle extends from -20 to 2 on the x-axis, with 1 as the interval. On the y-axis, it extends from -4 to 5, with 0.5 as the interval.

Step 1: Identify the x-axis limits

The x-axis limits of the viewing rectangle are given by the first two numbers in the array. In this case, the x-axis extends from -20 to 2.

Step 2: Identify the y-axis limits

The y-axis limits of the viewing rectangle are denoted by the last two numbers in the array. In this case, the y-axis extends from -4 to 5.

Step 3: Determine the intervals

The intervals of the x and y axes are given by the third number in each of its respective arrays. For the x-axis, the interval is 1. For the y-axis, the interval is 0.5.
