The function y = 4x-5 is given. Calculate the value of the function at x = -2 and x = 1.

The task is solved by substituting the values of the argument (x) and finding the corresponding value of the function (y).

1.x = -2.

y = 4 * x – 5 = 4 * (-2) – 5 = -8 – 5 = – 13.

2.x = 1.

y = 4 * x – 5 = 4 * 1 – 5 = 4 – 5 = -1.

Answer: for x = -2, the value of the function is (-13), for x = 1, the value of the function is (-1).
