<h3>Answer: 41 cm^2</h3>
Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
- The bottom rectangle has area of 4*8 = 32 cm^2
- The top rectangle has area of 3*3 = 9 cm^2
The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".
Answer:
3) ,
, or
(same thing)
4) or
(same thing)
5) or
(same thing)
Step-by-step explanation:
3) Domain represents the amount of -values in a function. The image shows that the function's arrows point in both directions (right and left), infinitely, so the domain would be
,
, or
(same thing).
4) Range represents the amount of -values in a function. The function goes downward forever (
) by the indication of an arrow and halts just under the y-axis (
). After combining these two inequalities, you see that the range is
or
(same thing).
5) The -intercept is where the function crosses the
-axis. In this function, the
-intercept is
or
(same thing).
