Given the piecewise function:

Let's select the graph which represents the function.
We have the graph below:
For f(x) = 3, the graph will be a horizontal line on y = 3 which has an open dot on x = 0 and a closed dot on x = -2
For f(x) = 1 if x = 0, the graph will have a closed dot located on the point (0, 1)
For f(x) = -(x + 1) if 0 < x ≤2, the graph will have a negative slope with an open dot on (0, -1) and closed dot on (2, -3)
ANSWER:
Graph B
Answer:
x = 1
Explanation:

Rule: log(a) + log(b) = log(ab)

cancel out log on both sides

relocate constant variable

take 3 as a common factor

divide both sides by 3

middle term split

factor common terms

collect into groups

set to zero

relocate variables

There must be a positive solution for log, so the solution is only x = 1
We have been given the function

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

Now, we simplify this step by step.
First of all
. Thus, we have

Now, we can easily simplify it by PEMDAS


Therefore, the value of f(3) is 98.
By simplifying this expression it comes down to be

Answer:
y = 55°
Step-by-step explanation:
You know the sum of angles in a triangle is 180°. So, ...
25° +30° +x = 180°
And, you know a linear pair of angles totals 180°:
x + y = 180°
Substituting for 180°, we have ...
25° +30° +x = x + y
Subtracting x from both sides, we get a relation that is useful to remember:
25° +30° = y
y = 55°
_____
This relation is usually described as ...
An exterior angle is equal to the sum of the remote interior angles.
