I need help I don’t understand

*Replace each "x" with the required numbers .

1) g (14) ; Ans;

___o_o___

2) f (-8) ; Ans;

___o_o___

3) j (3) ; Ans;

___o_o___

4) h (4) ; Ans;

___o_o___

5) f (2.8) ; Ans;

___o_o___

6) j(-5) ; Ans;

___o_o___

7) g(3/4); Ans;

___o_o__

8) [h(6.2)]² ; Ans;

___o_o___

9) j(2) + g(-3) ; Ans;

___o_o___

10) h(1) - f(-10) ; Ans;

**We look at the table. If f(4) or f(-2) is required, it came from f(x) by substitution each x with the required numbers, and the result is in the table f(x) .

***But if he says that f(x) is equal to a number, he means the resulting table f(x) and asks for the "x" that you take from the table "x" .

Table (1) Ans;

f(4) = –3

f(-2) = – 6

If f(x)= -3 ,then x = 4

If f(x) = 1 , then x = 3

___o_o___

Table (2) Ans;

f(4) = –7

f(-2) = 1

If f(x)= -3 ,then x = 0

If f(x) = 1 , then x = - 2

___o_o____

Table (3)Ans;

f(4) = 7

f(-2) = 3

If f(x)= -3 ,then x = 6

If f(x) = 1 , then x = 0
