por favorr

Answer 1

Resposta:

$f(x) = (x - 1)2 - (x - 7)2 = \\ f(x) = (x - 1) \times 2 - (x -7) \times 2 \\ (x -1 - ( \times - 7) \\x - 1x + 7 \\ 6 \\ (x - 1 - ( - x - 7) \times 2 \\ 6 \times 2 \\ 12 \\ f(x) = (x - 1) \times 2 - (x - 7)2 \\ f(x) = \frac{d}{dx}((x- 1) \times 2( x - 7) \times 2 \\ f(x) = \frac{d}{dx}(2x -2)(x - 1) \times 2 \\ f(x) = \frac{d}{dx}((x - 1) \times 2(x - 7) \times 2 \\ - (x - 1) \times 2 \\ - (2x - 7 \times 2) \\ - (2x - 14) \\ f(x) = \frac{d}{dx}((x - 1) \times 2 - (x - 7) \times 2 \\ f(x) = \frac{d}{dx}(2x - 2 - (2x - 14) \\ f(x) = \frac{d}{dx}(2x - 2 - 2x + 14) \\ f(x) = \frac{d}{dx}( - 2 + 14) \\ f(x) = \frac{d}{dx}(2x - 2 - 2x + 14) \\ - 2 + 14 \\ + (14 - 2) \\ 12 \\ f(x) = \frac{d}{dx}(2x - 2 - 2x + 14) \\ f(x) = \frac{d}{dx}(12) \\ f(x) = 0 \\ resposta \\ f(x) = 0$
