Question

considere a função f(x) = 31x + 25,calcule o valor de f(23) e f(34)

​

Answer 1

Primeira

$\sf f(x) = 31x + 25$

$\sf f(23) = 31\cdot 23 + 25$

$\sf f(23) = 713 + 25$

$\red{\sf f(23) = 738}$

Segunda

$\sf f(x) = 31x + 25$

$\sf f(34) = 31\cdot 34 + 25$

$\sf f(34) = 1.054 + 25$

$\red{\sf f(34) = 1.079}$
