What is the value of the fuction y= 1/8x -13 when x= -4

Answer 1

To find the value of the function y = 1/8x - 13 when x = -4, you simply substitute -4 for x in the equation:

y = 1/8(-4) - 13
y = -4/8 - 13
y = -1/2 - 13
y = -0.5 - 13
y = -13.5

Therefore, the value of the function when x = -4 is -13.5.
