Answer:
f(2) = 5
Step-by-step explanation:
<h3><u>
Definitions:</u></h3>
Input values = x-coordinates.
- The input values are also known as the <u>domain</u>, which is the set of all real numbers. With the domain of a function, you could substitute any real number into a given function for x and produce a valid output.
Output values = y-coordinates
- The <u>range</u> is the set of all real numbers that depend on the input values plugged into the function. Thus, the range represents the output (y-values) that corresponds to the input values used into the function.
<h3><u>
Function Notation:</u></h3>
- In the function notation f(x), <em>f</em> is the function name, and <em>x</em> is your <u>input variable</u>.
- <u>Output values</u> are also called <u>functional values.</u> You could use any letter to represent a function name, such as g(x), w(x), etc.,.
<h3><u>Explanations:</u></h3>
This particular question asks for you to identify the corresponding output (y-value) of the given input value, x = 2. If you look at the graph, the x-coordinate, x = 2, corresponds to the y-coordinate of 5.
Therefore, f(2) = 5.
Attached is an edited screenshot of the graph that you posted, where it shows where f(2) = 5 is located on the graph.
Answer:
The dimension of A is 38.17
Step-by-step explanation:
Using the sine law
a/sin A = b/ sin B
For the question In ΔABC, sin A=82, sin B=58, and b=27. Find the length of A.
a/sin A = b/ sin B
Sin A = 82
b = 27
Sin B = 58
a/ 82 = 27/58
58a = 27 ×82= 2214
a = 2214/58 = 38.1724= 38.17
This is going to be a 3-4-5 triangle, so it’s perimeter is 12.
Not 100% sure but I think that would be a 20%.
Answer:
EF, where E is at (1, 9) and F is at (2, 5)
Step-by-step explanation:
Slope = rise/run or y/x. In a coordinate, a point on a graph is represented as (x,y). When the slope is -4 (or -4/1), this means the y value will decrease (as it is negative) by 4 units, while the x value increases (as it is positive) by 1 unit. The line EF demonstrates the values (1, 9) and (2, 5). The difference between them is (1, -4) in (x, y) form.
