Question

Dada a função afim f (x)=7x-8 a) f (-2) b) f (1,4) c) f (-1,4) d) f (2-5) e)f(-1*4) f)f (1)f (1)+7 g) f(2)+f(14).f(-1)

Answer 1

Resposta:

a) (7 • -2) • -8 = -14 • -8 = 112

b) (7 • 1,4) • -8 = 9,8 • -8 = -78,4

c) (7 • -1,4) • -8 = -9,8 • -8 = 78,4

d) (7 • 2 • -5) • -8 = -70 • -8 = 560

e) (7 • -1⁴) • -8 = 7 • -8 = -56

f) (7 • 1 • 1 • 1 + 7) • -8 = 14 • -8 = -112

g) (7 • 2 + 14 • -1) • -8 = 0 • -8 = 0
