What is the value of the function y=18x−13 when x=−4 ?(1 point)
y = 18(-4) - 13
y = -72 - 13
y = -85
Therefore, the value of the function y = 18x - 13 when x = -4 is -85.
wrong
Apologies for the mistake. Let's correct the calculation:
y = 18x - 13
y = 18(-4) - 13
y = -72 - 13
y = -85
The value of the function y = 18x - 13 when x = -4 is -85.
