Question

Dada a função f:R->R, Rdefinida por f(x) = 3x4,
calcule f(0), f(1) f (-2), f(3).​

Answer 1

Boa Noite !!!

f(x) = 3x⁴

Trocamos x por cada valor pedido:

↓ ↓ ↓ ↓ ↓ ↓ ↓

f(0) = 3.0⁴

$\huge\boxed{\boxed{\boxed{\boxed{\sf f(0)=0 \checkmark }}}}$

________________________________________________________

f(1) = 3.1⁴

$\huge\boxed{\boxed{\boxed{\boxed{\sf f(1) = 3\checkmark }}}}$

________________________________________________________

f(-2) = 3(-2)⁴

f(-2) = 3.16

$\huge\boxed{\boxed{\boxed{\boxed{\sf f(-2)=48\checkmark }}}}$

__________________________________________________________

f(3) = 3.3⁴

f(3) = 3.81

$\huge\boxed{\boxed{\boxed{\boxed{\sf f(3)=243\checkmark }}}}$
