Option C:
The value of f(–6) is 6.
Solution:
Let f(x) = y.
The value of y is depend on the value of x.
Here x is independent variable and y is the dependent variable.
To find the value of f(–6):
f(–6) means, we should find the value of our function when x equals –6.
In the given image, see the line on the graph.
The value of x is –6, it is on the left side of the graph.
The value of y corresponding to x = –6 is 6.
y = 6 when x = –6.
So, f(–6) is 6.
Hence the value of f(–6) is 6.
Option C is the correct answer.
