For which function is [tex]f(5) = 2[/tex]?

A. [tex]f(x) = x - 3[/tex]
B. [tex]f(x) = \frac{7}{5}x - 5[/tex]
C. [tex]f(x) = 2x - 8[/tex]
D. [tex]f(x) = 5 - \frac{3}{2}x[/tex]



Answer :

To determine a function [tex]\( f(x) \)[/tex] such that [tex]\( f(5) = 2 \)[/tex], we can consider various possible forms of functions. Here, we'll construct one straightforward example of such a function.

1. Constant Function:
A simple function that satisfies [tex]\( f(5) = 2 \)[/tex] is a constant function. A constant function has the same output value irrespective of the input. In this case, we define:
[tex]\[ f(x) = 2 \][/tex]
For any value of [tex]\( x \)[/tex], the function always returns 2. Specifically, when [tex]\( x = 5 \)[/tex]:
[tex]\[ f(5) = 2 \][/tex]
Hence, the constant function [tex]\( f(x) = 2 \)[/tex] meets the requirement.

This is one example of many possible functions that could satisfy the condition [tex]\( f(5) = 2 \)[/tex]. Other forms could include piecewise functions or more complex definitions, but a constant function is the simplest and most straightforward example.
