Step-by-step explanation:
Given:
Input: left parenthesis x right parenthesis equals space 7 x minus 3
Mathematically:
Input: f(x) = 7x - 3
To find:
Output for the relation:
Solution:
We can find the output by substituting the value of the function which we need.
For 1st no,
f left parenthesis negative 2 right parenthesis
Mathematically:
f(-2)
Now substituting the value of x as -2.
[tex]\sf f(-2) = 7\times -2 -3 = -14-3 = -17[/tex]

For 2nd no,
f left parenthesis 3 right parenthesis
Mathematically:
f(3)
Now substituting the value of x as 3.
[tex]\sf f(3) = 7\times 3 -3 = 21-3 =18[/tex]

For 3rd no,
f left parenthesis 8 right parenthesis
Mathematically:
f(8)
Now substituting the value of x as 8.
[tex]\sf \sf f(3) = 7\times 8 -3 = 56-3 =53[/tex]
[tex]\hrulefill[/tex]
For 4th no,
f left parenthesis 7 right parenthesis
Mathematically:
f(7)
Now substituting the value of x as 7.
[tex]\sf \sf f(3) = 7\times 7 -3 = 49-3 =46[/tex]
Final answer:
[tex]\boxed{\begin{aligned} &\sf 1. f(-2) \longrightarrow c. -17\\& \sf 2. f(3) \longrightarrow b. 18 \\&\sf 3. f(8) \longrightarrow a. 53\\&\sf 4. f(7) \longrightarrow d. 46\\ \end{aligned}}[/tex]
1. f left parenthesis negative 2 right parenthesis - c. -17
2. f left parenthesis 3 right parenthesis - b. 18
3. f left parenthesis 8 right parenthesis - a. 53
4. f left parenthesis 7 right parenthesis - d. 46
Given :
- f(x) = 7x - 3
To find :
- f(-2)
- f(3)
- f(8)
- f(7)
Solution:
when f(-2)
- f(-2) = (7*-2) - 3
- f(-2) = -14 -3
- f(-2) = -17
when f(3)
- f(3) = 7*3 - 3
- f(3) = 21 -3
- f(3) = 18
when f(8)
- f(8) = 7*8 -3
- f(8) = 56 -3
- f(8) = 53
when f(7)
- f(7) = 7*7 - 3
- f(7) = 49 - 3
- f(7) = 46
