The value of f(-6) is -12.2
Explanation:
Given that the function 
We need to determine the value of f(-6)
The value of f(-6) can be determined by substituting the value for
in the function and simplify the function.
Hence, let us substitute
in the function, we get,

Let us apply the rule
, we get,

Multiplying the numbers, we get,

The value of 
Substituting the value of
, we get,

Subtracting the denominator, we have,

Dividing, we have,

Rounding off to the nearest tenth, we have,

Thus, the value of f(-6) is -12.2
I think it’s -1 because with rise/run it goes down 2 and over 2 but the line is going down, so it’s negative.
BECAUSE THERE IS A Y AXIS AND AN X AXIS THOSE R THE 2 GIVIN LINES
