Question

given: $f(x) = -3x - 5$
find: $f(-2)$
\\(\circ -10\\)
\\(\circ 1\\)
\\(\circ -11\\)
\\(\circ 0\\)

Explanation:

Step1: Substitute \( x = -2 \) into \( f(x) \)

We have the function \( f(x) = -3x - 5 \). To find \( f(-2) \), we replace \( x \) with \( -2 \) in the function. So we get \( f(-2) = -3\times(-2) - 5 \).

Step2: Calculate the expression

First, calculate \( -3\times(-2) \). Multiplying two negative numbers gives a positive result, so \( -3\times(-2)=6 \). Then we subtract 5 from 6: \( 6 - 5 = 1 \).

Answer:

\( 1 \) (corresponding to the option "1")
