f(x) = 25x + 65
f(2) = 25(2) + 65
f(2) = 50 + 65
f(2) = 115
f(x) = 25x + 65
f(4) = 25(4) + 65
f(4) = 100 + 65
f(4) = 165
f(x) = 25x + 65
f(5) = 25(5) + 65
f(5) = 125 + 65
f(5) = 190
MAKA :
F(2) + F(4) - F(5)
= 115 + 165 - 190
= 280 - 190
= 90
f(x) = 25x + 65
f(2) = 25 ( 2 ) + 65
f(2) = 50 + 65
f(2) = 115
___________
f(x) = 25x + 65
f(4) = 25 ( 4 ) + 65
f(4) = 100 + 65
f(4) = 165
___________
f(x) = 25x + 65
f(5) = 25 ( 5 ) + 65
f(5) = 125 + 65
f(5) = 190
Jadi :
f(2) + f(4) - f(5)
115 + 165 - 190
280 - 190
90
