Answer:
*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;
___________o____o__________
**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" .
<u>Table (1) Ans;</u>
f(4) = <u> –3</u>
f(-2) = <u>– 6</u>
If f(x)= -3 ,then x = <u>4</u>
If f(x) = 1 , then x = <u>3</u>
___o_o___
<u>Table (2) Ans; </u>
f(4) = <u>–7</u>
f(-2) = <u>1</u>
If f(x)= -3 ,then x = <u>0</u>
If f(x) = 1 , then x = <u>- 2</u>
___o_o____
<u>Table (3)Ans;</u>
f(4) = <u>7</u>
f(-2) = <u>3</u>
If f(x)= -3 ,then x = <u>6</u>
If f(x) = 1 , then x = <u>0</u>
