Average = Mean
To find the mean, add up the numbers and divide it by how many numbers there are.
So,
There are 5 numbers in total.
To do these types of division, ignore the decimal and add a 0 at the end.
So we can do:
And put back the decimal.
Hope this helps :)

We will see that g(x) is a reflection across the y-axis of f(x), then:
<h3>How to identify the function g(x)?</h3>
By looking at the graph, we can see that g(x) is a reflection across the y-axis of f(x).
So we can write:
g(x) = f(-x)
Here we know that:
Then, replacing f(x) on the formula for g(x), we get:
That is the function g(x) shown in the figure.

Answer:
1/4
Step-by-step explanation:
The tangent line to f(x) at x=2 goes through the point (2, 8) and has slope 4.
The inverse function f⁻¹(x) is a reflection of the function f(x) across the line y=x. The corresponding tangent line will go through point (8, 2) and have slope 1/f'(2) = 1/4 at that point. That is, ...
(f⁻¹)'(8) = 1/f'(f⁻¹(8)) = 1/f'(2) = 1/4
