Tolong yang A itu jawabannya apa,bingung

FUngsi komposisi

f(x)= 2x² + x
g(x)= 3x - 2

a. fog(2) = f { g(2)} = f (3(2) - 2) = f(4)
fog(2)= f(4) = 2.4² + 2 = 34

b.gof(-2) = g{f(-2)} = g (2(-2)²+2) = g(10)
gof(-2) = g(10) = 3(-10) - 2 = - 32

c. fof (1) =  f{ f(1)} = f(2(1)²+1) = f(3)
fof(1) =f(3) =  2.3² + 3 = 21

d. gog (2) = g { g(2)} = g (3(2) - 2) = g(4)
gog(2)= g(4) = 3(4)  - 2 = 10
