Step-by-step explanation:

let x be total much won

so they team had won 28 matches.
I hope the team has best players : )
F(3) = 2(3)^2 - 3(3) + 1 = 18 - 9 + 1 = 10
f(2) = 2(2)^2 - 3(2) + 1 = 8 - 6 = 2
Then f(3) - f(2) = 10 - 2 = 8 (answer)
A) f + s + t = 148
B) f + 10 = s
C) t = 4 * f
Substituting C) into A)
A) f + s + 4f = 148
Substituting B) into A)
A) f + f + 10 + 4f = 148
A) 6f = 138
f = 23
B) f + 10 = s
s = 33
t = 4 * 23
t = 92
23 + 33 + 92 = 148
g(x) –f(x) = 3x –9 - (<span>5x –1)
</span> g(x) –f(x) = 3x –9 - 5x + 1
g(x) –f(x) = -2x - 8
