The value of f –1(13) is 4
<h3>How to determine the inverse value?</h3>
The table of values is given as:
x –4 0 2 5 9 13
f (x) –11 1 7 16 28 40
A linear function is represented as:
y = mx + b
Where b represents the y-intercept and m represents the slope
From the graph, when x = 0, y = 1.
This means that b = 1
So, we have
y = mx + 1
Also from the graph, when x = 2, y = 7.
So, we have:
7 = 2m + 1
Subtract 1 from both sides
7 - 1 = 2m + 1 - 1
Evaluate the difference
6 = 2m
Rewrite the above equation as:
2m = 6
Divide both sides of the equation by 2
m = 3
Substitute m = 3 in y = mx + 1
y = 3x + 1
The notation f –1(13) implies that y = 13
So, we have
13 = 3x + 1
Subtract by 1
3x = 12
Divide by 3
x = 4
Hence, the value of f –1(13) is 4

Step-by-step explanation:
In mathematics, WHOLE NUMBERS are the basic counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on. Whole numbers are the real numbers which includes zero and all the positive integers. Whole numbers don't include negative numbers, fractions, or decimals.
Answer:
Step-by-step explanation:
Let us assume that the eagle's elevation is 100 meters above.
We can multiply -14.2 by 0.8.
We now get -11.36.
We can add this to (-14.2*4).
We now get -11.36 + -56.8.
We can add those together to get the answer.
-11.36 + -56.8 = -68.16.
Then we can add that to 100 (since it is negative).
100 + (-68.16) = 31.84.
The eagle's elevation would be 31.84 meters if its starting position was 100 meters, meaning that the equation would be (a - 68.16).
The answer is
B. 3
