The expression that best predicts the end behavior of the graph of f(x) is the option
As x → ∞, f(x) → -∞, and as x → -∞, f(x) → ∞
The reason why the selected option is correct is given as follows:
Question options; The question options include;
As x → ∞, f(x) → ∞, and as x → -∞, f(x) → ∞
As x → ∞, f(x) → ∞, and as x → -∞, f(x) → -∞
As x → ∞, f(x) → -∞, and as x → -∞, f(x) → ∞
As x → ∞, f(x) → -∞, and as x → -∞, f(x) → -∞
The given data in the table are presented as follows;
From the data, we have;
As x increases to -∞, f(x) increases to ∞, therefore, we have;
x → -∞, f(x) → ∞
Similarly, we have;
As x → ∞, f(x) → -∞
Therefore, the end behavior of the graph is as x → ∞, f(x) → -∞, and as x → -∞, f(x) → ∞

Ответ:
- When the values of x ⇒ -∞, f(x) ⇒ +∞
- When the values of x ⇒ +∞, f(x) ⇒ -∞
Step-by-step explanation:
* Lets explain the end behavior of the graph of a function
- The end behavior of a function f describes the trend of the graph
if we look to the right end of the x-axis as x approaches ∞ and
to the left end of the x-axis as x approaches -∞
- Lets look to the table of the function
x f(x)
-4 18
-3 9
-2 6
-1 3
0 0
1 -3
2 -6
3 -9
4 -18
* From the table we notice that
- The values of x from -4 to zero have positive values of f(x)
- The values of x from 0 to 4 have negative values of f(x)
∴ When x increased from negative to positive y decreased from
positive to negative
- That means when x values go to -∞ the corresponding values of
f(x) go to +∞ and when x values go to +∞ the corresponding values of
f(x) go to -∞
∴ The end behavior of the graph of f(x) is
- When the values of x ⇒ -∞, f(x) ⇒ +∞
- When the values of x ⇒ +∞, f(x) ⇒ -∞
Ответ:
f(x)=(x+1)^2-2 is the minimum and g(x)=-(x-2)^2+1 is the maximum
Step-by-step explanation:
Looking at the graph, (you should be able to graph this) the parabola for f(x)=(x+1)^2-2 is pointing downwards and stops at the vertex. This vertex is negative which is the lowest point possible which makes it the minimum. The parabola for -(x-2)^2+1 is pointing upwards and stops at the vertex which is the highest point possible which makes it the maximum.
