If [tex]f(x) = 3 - 2x[/tex] and [tex]g(x) = 2x[/tex], what is the value of [tex]f(20)[/tex]?

A. -37
B. -57
C. 17
D. -17

Answer :

Final answer:

To find the value of f(20) for the function f(x) = 3 - 2x, we substitute x with 20 in the equation and simplify to get -37, which is option a).

Explanation:

The question asks to find the value of f(20) where the function f(x) = 3 - 2x. The value of x is given as 20. To find the value of f(20), we substitute 20 into the equation for x.

Step 1: Substituting x with 20, we get: f(20) = 3 - 2 * 20.

Step 2: Simplifying the equation, we get: f(20) = 3 - 40 = -37.

Therefore, the value of f(20) when f(x) = 3 - 2x is -37, which corresponds to option a) -37.
