Question

What is the value of the function y=18x−13 when x=−4 ?(1 point) Responses −13.5 negative 13.5 −16 negative 16 −12.5 negative 12.5 −15

Answer 1

thats not correct

Answer 2

To find the value of the function, y = 18x - 13, when x = -4, substitute -4 in place of 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.
