To find the value of the function y = (1/8)x - 13 when x = -4, we substitute -4 for x in the equation.
y = (1/8)(-4) - 13
= (-4/8) - 13
= -1/2 - 13
= -14/2 - 13
= -7 - 13
= -20
Therefore, when x = -4, the value of the function y = (1/8)x - 13 is -20.
What is the value of the function y=1/8x-13 when x=-4?
