To find the value of the function y = 18x - 13 when x = -4, we substitute -4 for x in the equation.
y = 18(-4) - 13
y = -72 - 13
y = -85
Therefore, the value of the function y = 18x - 13 when x = -4 is -85.
What is the value of the function y=18x−13 when x=−4 ?

Apologies for the confusion. Let's re-evaluate the equation.
Given: y = 18x - 13
Substituting x = -4:
y = 18(-4) - 13
y = -72 - 13
y = -85
Hence, the correct value of the function y = 18x - 13 when x = -4 is indeed -85.
