Answer 3

To find the values of the function y = -3x - 1 at the given values of x, substitute each x-value into the equation and calculate the corresponding y-values.

For x = -1: y = -3(-1) - 1 = 3 - 1 = 2

For x = 2: y = -3(2) - 1 = -6 - 1 = -7

For x = 4: y = -3(4) - 1 = -12 - 1 = -13

Therefore, the values of the function y = -3x - 1 at x = -1, 2, and 4 are: y = 2 when x = -1 y = -7 when x = 2 y = -13 when x = 4
