Question

sendo f (x) = x elevado a 2 : a ) x=(-1,0,3,4,7)
​

Answer 1

Resposta:

F(x) = x² + 7x + 10

a) f(0) =0² + 7.0 + 10  = 10

b) f(1) = 1² + 7.1 + 10 = 1 + 7 + 10 = 18

c) f(2) = 2² + 7.2 + 10 = 4 + 14 + 10 = 28

d) f(-1) = (-1)² + 7.(-1) + 10 = 1 - 7 + 10 = 4

e) f(-3) = (-3)² + 7(-3) + 10 = 9 - 21 + 10 = -2

f) f(-5) = (-5)² + 7(-5) + 10 = 25 - 35 + 10 =0
