Question

Se f (x)=5x+1 e h (x)2=1+4x2 calcular f (h (2))+h (f (2))

Answer 1

Se f (x)=5x+1 e h (x)2=1+4x2 calcular f (h (2))+h (f (2))
f (x)=5x+1      h (x)2=1+4x2 


h(2) = 1 + 4.2^2 ==> 1 + 16 ==> 17

f (h (2)) = f(17) = 5.17.+1 ==> 85+1, então f(h(2)) = 86
===========================================
h (f (2))

f(2) = 5.2 + 1 ==> 10 + 1 ==> 11

h(f (11)) = h(17) = 1 + 17^2 ==> 1+289, então h(f(2)) = 289
==================================================

f (h (2))+h (f (2)) =  86 + 289 ==> 375
