The function is given by the formula y = 2x + 7. Find the function value corresponding to the argument

The function is given by the formula y = 2x + 7. Find the function value corresponding to the argument value equal to 1; -twenty; 43.

The value of the function is the value of y, the value of the argument is the value of x. Thus, you just need to substitute the specified values for x.

1. Argument value = 1; y (1) = 2 * 1 + 7 = 2 + 7 = 9;

2. The value of the argument = -20; y (-20) = 2 * (-20) + 7 = -40 + 7 = -33;

3. The value of the argument = 43; y (43) = 2 * (43) + 7 = 86 + 7 = 93.
