| **The function is given by the formula y = x-7 find the value a) the value of the function corresponding to the value of the argument equal to 4. b) the value of the argument at which the value of the function is equal to.**

For a function y = f (x), x is the argument and y is the function value for the given x argument.

A) If the argument x = 4, then for the value of the function y we get:

y = x – 7 = 4 – 7;

y = -3;

C) If the value of the function y = -8, then for the argument x we get:

y = x – 7;

x = y + 7 = -8 + 7;

x = -1;

Answer: A) y = -3; B) x = -1
