The value of the function y = 1/8x - 13 when x = 4 can be found by substituting x = 4 into the equation and evaluating.

y = 1/8(4) - 13
y = 1/2 - 13
y = -12.5 - 13
y = -25/2 - 26/2
y = -51/2

Therefore, the value of the function is approximately -25.5.

None of the provided answer choices match this value, so the correct answer is not given.

Apologies for the misunderstanding.

To find the value of the function y = 1/8x - 13 when x = 4, we substitute x = 4 into the equation and evaluate:

y = 1/8(4) - 13
y = 1/32 - 13
y ≈ -12.59

Approximating to two decimal places, the value of the function when x = 4 is approximately -12.59.

Among the answer choices given, the closest value is -12.5. Therefore, the correct answer would be -12.5.
