Question

Seja f: R→R uma função definida por: f(x)= x² - 3x - 10, calcule:
a) f(-2)
b) f(-1)
c) f(0)
d) f(3)
e) f(1/2)

Answer 1

F(-2) -2^2 -3(-2) -10
F(-2) = 0

F(-1) = -1^2 -3(-1) -10
F(-1) = -6

F(0) = 0^2 -3(0) - 10
F(0) = -10

F(3) = 3^2 -3.3 - 10
F(3) = -10

F(1/2) = 1/2^2 - 3.1/2 - 10
F(1/2) = -12/4
