4 −15

Answer 1

The value of the function y = 18x - 13 when x = -4 can be found by substituting -4 into the equation:

y = 18(-4) - 13

y = -72 - 13

y = -85

Therefore, the value of the function is negative 85.

Answer 3

Apologies for the confusion. I made a mistake in my calculation.

To find the value of the function y = 18x - 13 when x = -4, we substitute -4 into the equation:

y = 18(-4) - 13

y = -72 - 13

y = -85

Therefore, the correct value of the function is -85.
