f(x) = 3x + 2
g(x) = 4x - 3
nilai f(x + 1) + g(x) = ...![]()
[tex]~[/tex]
f(x) = 3x + 2
g(x) = 4x - 3
nilai f(x + 1) + g(x) = ...
Diketahui:
- f(x) = 3x + 2
- g(x) = 4x - 3
Ditanya:
- f(x + 1) + g(x)
Jawab:
Nilai f(x + 1).
f(x) = 3x + 2
f(x + 1) = 3(x + 1) + 2
f(x + 1) = 3x + 3 + 2
f(x + 1) = 3x + 5
Maka nilai dari f(x + 1) + g(x):
f(x + 1) + g(x)
= 3x + 5 + 4x - 3
= 3x + 4x + 5 - 3
= 7x + 2
Koreksi kakak....
f(x + 1) + g(x)
3x + 2 + 4x - 3
( 3 ( x + 1 ) + 2 ) + 4x - 3
3x + 3 + 2 + 4x - 3
3x + 4x + 3 + 2 - 3
7x + 5 - 3
7x + 2
