The items below discuss each choices and states whether the statements are true or false.
(A) It can be seen from the table that if the value of x is -2 then, the value of y is 6. Therefore, this statement is TRUE.
(B) The term range refers to the values of y that can be the result of substituting any x value to the equation generated from the given data. As per table, it can be seen that the values of y can range from negative infinity to positive infinity so long as the number of real. This statement is TRUE.
(C) The choice says f(5) = -2. This statement is FALSE because it should be written as, f(-2) = 5 given that x is the independent variable and y or f(x) is the dependent variable.
(D) The domain is the range of number that the values of x may take. As per the table, the domain is at -2 to 6. Therefore, this statement is TRUE.
You have to know the coordinates of the center and the radius.

Tthe 2 adjacent angles add up to 109 degrees.
so x + 91 + 101 + x = 180
2x + 192 = 180
2x = -12
x = -6 (answer)
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
