The given function is a linear function that decreases as the value of the
input <em>x</em> increases.
- The value of f(10), given f(x) = 9 - 2·x is option <u>A. -11</u>
Reasons:
The given function is f(x) = 9 - 2·x
The output of the function is the value of f(x) for a given input <em>x</em> of the function.
The input value, <em>x</em> is substituted into the function to obtain the output value, f(x).
Given that the input, x = 10
We have;
f(10) = 9 - 2×10 = -11
Therefore, the correct option for f(10) is <u>A. -11</u>
