Answer:
4 + √15
Step-by-step explanation:
Conjugate means flip the sign. For example, 1 + 1 ⇒ 1 - 1.
A) the x-values on the graph are [-2, 4].
all the x-values of the graph are the Domain of the function of the graph. they are found by projecting the graph to the x-axis. check the yellow line in the first picture.
b) all the possible outputs of g are [-1, 3].
all the possible outputs of g, are the Range of g. These are found by projecting the graph to the y-axis. check the red line in the second picture.
c) -1 , 0, 1, 2, and 3 are only a few values in the Range. The range is [-1, 3].
d) we will sketch a graph whose domain is [-2, 4] and range is [-1, 3]. check picture 3
Answer:
lesser x = -6
greater x = 12
Step-by-step explanation:
(x - 3)^2 - 81 = 0
(x - 3)^2 = 81
x - 3 = +/- 9
x - 3 = 9 or x - 3 = -9
x = 12 or x = -6
The area of the first rectangle would be 18cm² and the area of the second rectangle would be 12cm².
<h3>How to calculate the area of a rectangle?</h3>
To calculate the area of a rectangle we must apply the following mathematical formula:
According to the above, to calculate the area of the rectangles we must multiply the length of the side by the base as shown below. We must also take into account the table that will give us the value of X that we do not know:
- 3cm × 6cm = 18cm²
- 2cm × 6cm = 12cm²
Finally, to know how much the area of both rectangles adds up, we add both values:
12cm² + 18cm² = 30cm²
Note: This question is incomplete because the graph is missing. Here is the graph
