4/3
-72
4
4/9

Answer 1

hey there!
here given equation is y= 12×3x

and here x= -2

so now put the value of x in equation

y = 12×3×-2
y=-72

Answer 2

To evaluate the function rule of the given value, you have to follow these steps.

The given equation is y = 12 x 3x and given x value is -2.

As per the basic function rule, you have to put the known variable value in the given equation to find the unknown value of another variable.

To do so, we get, y = 12 x 3 x -2 => - 72.

Hence, the value of y = -72.
