Question

2) Considere a função f(x) = 3x+1. a) f(0) b) f(2) c) f(-2) d) f(0,5) e) n tal que, f(n) = 21​

Answer 1

f(x)=3x+1

a) se o x for 0

f(0)= 3.0 +1

0+1

1#

b) se o x for 2

f(2)= 3.2+1

6+1

7#

c) se o x for -2

f(-2)=3.(-2)+1

-6+1

-5#

d) se o x for 0,5

f(0,5) = 3.0,5+1

1,5+1

2,5#
