Question

de 4 valores para X na função F(x)=10-2x BRAINLY

Answer 1

1)

$f(0) = 10 - 2 \times 0 \\ f(0) = 10$

2)

$f( - 2) = 10 - 2 \times ( - 2) \\ f( - 2) = 10 + 4 \\ f( - 2) = 14$

3)

$f(10) = 10 - 2 \times 10 \\ f(10) = 10 - 20 \\ f(10) = - 10$

4)

$f(2) = 10 - 2 \times 2 \\ f(2) = 10 - 4 \\ f(2) = 6$
