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

Answer 1

To find the value of the function when x = -4, we substitute -4 for x in the function and evaluate:
y = 1/8(-4) - 13
y = -1/2 - 13
y = -1/2 - 26/2
y = -27/2 or -13.5

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