What is the value of the function y=1/8x−13 when x=−4?

Question

−13.5 −15 −16 −12.5

Answer 1

To find the value of the function y when x = -4, we substitute -4 for x in the function:

y = (1/8)(-4) - 13

Calculating, we have:

y = -1/2 - 13 = -1/2 - 26/2 = -27/2 = -13.5

Therefore, when x = -4, the value of the function y = 1/8x - 13 is -13.5.
