What is the value of the function y=18x−13 when x=−4 ?(1 point)Responses-15 -16 -12.5 -13.5
To find the value of the function when x = -4, we can substitute -4 for x in the equation:
y = 18x - 13
y = 18(-4) - 13
y = -72 - 13
y = -85
Therefore, the value of the function y = 18x - 13 when x = -4 is -85.
