Question

porfavor me ayudan:((​

Answer 1

Respuesta:

f(1) = 30

f(7) = 0

f(0) = 42

f(-1) = 40

Explicación:

f(x) = x³ - 7x² - 6x + 42

f(1) = 1³ - 7(1)² - 6(1) + 42

f(1) = 1 - 7 - 6 +42

f(1) = 30

f(7) = 7³ - 7(7)² - 6(7) + 42

f(7) = 343 - 7(49) - 42 +42

f(7) = 0

f(0) = 0³ - 7(0)² - 6(0) + 42

f(0) = 0 - 0 - 0 +42

f(0) = 42

f(-1) = (-1)³ - 7(-1)² - 6(-1) + 42

f(-1) = -1 - 7 + 6 +42

f(-1) = 40
