What is the value of the function y=1/8x−13 when x=−4 ?(1 point) Responses −15 negative 15 −13.5 negative 13.5 −12.5 negative 12.5 −16
To find the value of the function, we substitute x=-4 into the expression for y:
y = (1/8)x - 13
y = (1/8)(-4) - 13
y = -1/2 - 13
y = -1/2 - 26/2
y = -27/2
Therefore, when x=-4, the value of the function y=1/8x−13 is -27/2 or -13.5.
