1 answer:
Answer:
D. x=29.37
Step-by-step explanation:
To answer this question you have to understand how log work. Log is the abbreviation of logarithm and it works as an inverse function of exponentiation.
The rules should be like this:
Variable a in the equation is called base. If it left empty you can assume its base 10. The log in this question using 5 as a base. Variable b will be x and variable c will be 2.1

Answer:
1) Please see the required graph created with Microsoft Excel
2) No
Step-by-step explanation:
The given parameters are;
From the given equation, we have;
When x > 4, or x -2 <, y < 0, which gives;
y > 0 for -2 < x < 4
Therefore, the graph is opened in the downward direction with the peak at the point with coordinate (1, 3)
The legs of the graphs are straight lines with slopes = -1, and 1 respectively, before and after the maximum point of the graph
The table of values used to sketch the graph with Microsoft Excel is given as follows;
x y
-3 -1
-2 0
-1 1
0 2
1 3
2 2
3 1
4 0
5 -1
