Domain and range:
The domain of a function is all the values the the input assumes.
The range of a function is given by all the values that the output assumes.
In a graphic:
The domain is given by the x-values, the horizontal axis.
The range is given by the y-values, the vertical axis.
In this question:
x, in the horizontal axis, assumes values between -4 and 2.
The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.
Thus, the domain of the graphed function is: , and the correct answer is given by option D.

The output of the function when x=4 is 23
<h3>How to determine the output</h3>
Given the function as;
f(x)=4x+7
We are told to find f ( 4)
This explains that we should substitute the value of x as 4 in the function:
To find the value of the function at x = 4 we have:
If f(x)=4x+7
Then,
Put 4 as a replacement for x, we have:
f ( 4) = 4 ( 4) + 7
Expand the bracket
f ( 4) = 16 + 7
Add the values
f ( 4) = 23
The value of the function is 23
We can see that the value of the function when x is 4 is 23
Thus, the output of the function when x=4 is 23
The complete question is;
For each function what is the output for the given input?
For f(x)=4x+7, find f(4)

2.)112
3.)99
I think these are right
Step-by-step explanation:
The two triangles are similar by SSA similarity. Option B is correct.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.
From the triangle ABC and DEC
The ratio of the sides is;
One angle c is common in the two triangles.
The two triangles are similar by SSA similarity.
Hence, option B is correct.
