Question

find f( - 4), f(0) and f(1) for the following function. f(x) = 2x f( - 4) = \square

Explanation:

Step1: Substitute x = -4 into f(x)

To find \( f(-4) \) for the function \( f(x) = 2x \), we substitute \( x = -4 \) into the function. So we have \( f(-4)=2\times(-4) \).

Step2: Calculate the result

Calculating \( 2\times(-4) \), we know that a positive number multiplied by a negative number gives a negative result. So \( 2\times(-4)= -8 \).

Answer:

\( f(-4)= -8 \)
