For the function \( f(x) = 8x - 6 \), we note that it is a linear function, which means it has no critical points since its derivative (which is the slope, 8) does not equal zero. Therefore, the absolute maximum and minimum can be found by evaluating the function at the endpoints of the intervals. (A) For the interval \([0, 4]\): - Evaluate \( f(0) = 8(0) - 6 = -6 \) - Evaluate \( f(4) = 8(4) - 6 = 26 \) Thus, the absolute maximum value is \( 26 \) at \( x = 4 \) and the absolute minimum value is \( -6 \) at \( x = 0 \). (B) For the interval \([-4, 2]\): - Evaluate \( f(-4) = 8(-4) - 6 = -38 \) - Evaluate \( f(2) = 8(2) - 6 = 10 \) Therefore, the absolute maximum value is \( 10 \) at \( x = 2 \) and the absolute minimum value is \( -38 \) at \( x = -4 \). **Summary:** (A) The absolute maximum value is \( 26 \) at \( x = 4 \). The absolute minimum value is \( -6 \) at \( x = 0 \). (B) The absolute maximum value is \( 10 \) at \( x = 2 \). The absolute minimum value is \( -38 \) at \( x = -4 \).
