Question

Dada a função f: R R definida por f(X) 4X+32 DETERMINE
a) f(0)
b)f(7)
c)f(-3)

Answer 1

Olá!!!

Resoluçao!!!

f ( x ) = 4x + 32

a)

• f ( 0 )

f ( x ) = 4x + 32
f ( 0 ) = 4 • ( 0 ) + 32
f ( 0 ) = 0 + 32
f ( 0 ) = 32

b)

• f ( 7 )

f ( x ) = 4x + 32
f ( 7 ) = 4 • ( 7 ) + 32
f ( 7 ) = 28 + 32
f ( 7 ) = 60

c)

• f ( - 3 )

f ( x ) = 4x + 32
f ( - 3 ) = 4 • ( - 3 ) + 32
f ( - 3 ) = - 12 + 32
f ( - 3 ) = 20

Espero ter ajudado!!!
