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