Question: 1 / 400

What is the value of the function f(x) = -2x + 1 when x is equal to 1?

To find the value of the function $ f(x) = -2x + 1 $ when $ x = 1 $, you need to substitute 1 for $ x $ in the equation.

Start by substituting:

f(1) = -2(1) + 1

This simplifies as follows:

f(1) = -2 + 1

Now, combine the numbers:

f(1) = -1

This means the value of the function when $ x = 1 $ is -1. Therefore, the correct answer is -1, which reflects the output of the function for the given input.

It's important to carefully evaluate the function step by step to ensure that you arrive at the correct numerical result. This method of substitution is fundamental in understanding how functions operate when specific values are input.
