Dada a função f(x) = 2x + 3, calcule:

a) f(0) + f(1)

= (2•0 + 3) + (2•1 + 3)

= 0 + 3 + 2 + 3

= 3 + 5

= 8 ,,,,

b) f(–1) + f(2)

= ( 2(–1) + 3 ) + (2•3 + 3)

= –2 + 3 + 6 + 3

= 1 + 9

= 10,,,,

c) f(–1) + 2f(0)

= ( 2(–1) + 3) + 2(2•0 + 3)

= –2 + 3 + 2(0 + 3)

= –2 + 2 • 3

= –2 + 6

= 4,,,,


Espero ter ajudado!
Ótimos estudos :)
