Transcribed Image Text:**Question:** What is the value of \( f(x) = 4x + 2 \) when \( x = 5 \)? **Options:** - \( -22 \) - \( -20 \) - \( -18 \) - \( 22 \)
**Question:** For the function \( f(x) = 2 - 3x \), find \( f(4) \). **Answer Choices:** - \( -10 \) - \( -5 \) - \( 12 \) - \( 14 \) **Solution:** To find \( f(4) \), substitute \( 4 \) into the function \( f(x) = 2 - 3x \): \[ f(4) = 2 - 3(4) \] \[ = 2 - 12 \] \[ = -10 \] Thus, the correct answer is \( -10 \).
