Lisa wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then employed the results and connected them with a line, as shown in the picture. The graph shows the area (in m2) versus the length (in m) a. Domain:
b. Range

(Sorry I keep asking so many questions it’s because these questions are questions of things I have NEVER learned at all yet and it is a new module. When people explain and show me the work I write them in my book with the explanations as well when people put them down and that is how I start to learn this ahead of time.)

The domain and range of the function shown is

domain  

range

Given :

The graph of  the area of a rectangle changes with the length if it’s width is fixed

We need to find out the domain and range from the given graph

Domain is the set of x values on the graph

We can say the graph starts at x=0  and it goes up to infinity

So, domain is

Range is the set of y values for which the function defined

Range is the set of y values on graph

When we look at y values , the graph starts at y=0 and it goes up to infinity

So, range is

Domain: interval: [0,∞], Words: All real numbers greater than or equal to 0, Inequality: x≥0.

Range: interval: [0,∞], Words: All real numbers greater than or equal to 0, Inequality: y≥0.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
