What is the value of the function y=◂−▸ 1 8 x−13 when x=−4? Responses −16 16 −13.5 13.5 −12.5 12.5 −15
To find the value of the function when x = -4, we substitute -4 for x in the equation:
y = -1/8x - 13
y = -1/8(-4) - 13
y = 1/2 - 13
y = -12.5
Therefore, the value of the function y = -1/8x - 13 when x = -4 is -12.5.
