Respuesta :

f(x)=2x+5
g(x)=3x³+2x+4

if f(g)(2) = ?????

f(g)(x)=2(3x³+2x+4)+5
f(g)(x)=6x³+4x+8+5
f(g)(x)=6x³+4x+13


f(g)(2)=6(2)³+4(2)+13
f(g)(2)=6•8+8+13
f(g)(2)=69

f(x) = 2x + 5
g(x) = 3x³ + 2x + 4

f(g(2)) = 2(3(2)³ + 2(2) + 4) + 5
f(g(2)) = 2(3(8) + 4 + 4) + 5
f(g(2)) = 2(24 + 8) + 5
f(g(2)) = 2(32) + 5
f(g(2)) = 64 + 5
f(g(2)) = 69
