Question

Dada a função f(x) = 2x - 1, determine:
a) f(2)
b) f(-1)
c) f(1)
d) f(0)
e) f(22)​

Answer 1

Resposta:

f(x) = 2x - 1

a) f(2) = 2 . (2) - 1

f(2) = 4 - 1

f(2) = 3

b) f(-1) = 2 . (-1) - 1

f(-1) = -2 - 1

f(-1) = -3

c) f(1) = 2 . (1) - 1

f(1) = 2 - 1

f(1) = 1

d) f(0) = 2 . (0) - 1

f(0) = 0 - 1

f(0) = - 1

e) f(22) = 2 . (22) - 1

f(22) = 44 - 1

f(22) = 43
