Question

Considere a função
f(x)= 4x+9, determine.


a)f(2)

b)f(-3)

c)f(0)

Answer 1

Olá...

f(x) = 4x + 9

a) f( 2 )

f (2) = 4.2 + 9

f(2) = 8 + 9

f(2) 17

 

b) f(- 3)

f(- 3) = 4.(- 3) + 9

f(- 3) = - 12 + 9

f(- 3) = - 3

c) f( 0 )

f( 0 ) = 4. ( 0 ) + 9

f( 0 ) = 0 + 9

f( 0 ) = 9

Bons estudos.
