To find if the functions are increasing, decreasing, positive or negative, relative

Answer to Problem 44HP
The functions are increasing, positive, has no maxima and minima and no symmetry.
Explanation of Solution
Given:
Function:
Concept used:
Maxima is the highest value of a function and minima is the lowest point of a function.
Symmetry is the condition wherein the axes cut the curve equally.
The end behavior of a function is the behavior of the graph at the ends of the x- axis.
Calculation for graph:
Consider
Values of x | ||
-5 | 1.09 | -14 |
-4 | 1.18 | -11 |
-3 | 1.37 | -8 |
-2 | 1.75 | -5 |
-1 | 2.5 | -2 |
0 | 4 | 1 |
1 | 7 | 4 |
2 | 13 | 7 |
3 | 25 | 10 |
4 | 49 | 13 |
By taking different values of x , the graph can be plotted.
Graph:
Interpretation:
From the graph the red line represents
The y- intercept of
Conclusion:
Therefore, the function is increasing, positive, has no maxima and minima and no symmetry.
