Dialogue: 0,0:00:00.37,0:00:06.43,Default,,0000,0000,0000,,-2 · f(-6) + g(1) 의 값을 구해봅시다
Dialogue: 0,0:00:06.43,0:00:10.69,Default,,0000,0000,0000,,여기 아래에 f(x) 와 g(x) 의\N그래프가 있습니다
Dialogue: 0,0:00:10.70,0:00:12.17,Default,,0000,0000,0000,,이것을 어떻게 구할 수 있을지 봅시다
Dialogue: 0,0:00:12.17,0:00:16.37,Default,,0000,0000,0000,,먼저 f(-6) 이 무엇인지 \N계산해야 합니다
Dialogue: 0,0:00:16.37,0:00:19.55,Default,,0000,0000,0000,,함수에 x 대신 -6 을 대입합니다
Dialogue: 0,0:00:19.55,0:00:22.36,Default,,0000,0000,0000,,x 값은 가로축 위에 \N있다고 생각할 수 있습니다
Dialogue: 0,0:00:22.36,0:00:24.04,Default,,0000,0000,0000,,-6을 축에서 찾습니다
Dialogue: 0,0:00:24.04,0:00:31.57,Default,,0000,0000,0000,,함수의 정의에 의해\Nf(-6) = 7 입니다
Dialogue: 0,0:00:31.57,0:00:35.56,Default,,0000,0000,0000,,f(-6) = 7
Dialogue: 0,0:00:35.56,0:00:39.100,Default,,0000,0000,0000,,g(1) 은 무엇일까요?
Dialogue: 0,0:00:39.100,0:00:45.40,Default,,0000,0000,0000,,여기 축에서 찾으면\Ng(1) 의 값은
Dialogue: 0,0:00:45.40,0:00:48.44,Default,,0000,0000,0000,,-5 입니다
Dialogue: 0,0:00:48.44,0:00:52.10,Default,,0000,0000,0000,,g(1) = -5
Dialogue: 0,0:00:52.10,0:00:55.26,Default,,0000,0000,0000,,그러면 이 식은\N-2 × f(-6)이 됩니다
Dialogue: 0,0:00:55.26,0:00:59.62,Default,,0000,0000,0000,,f(-6)= 7 이니까
Dialogue: 0,0:00:59.63,0:01:02.95,Default,,0000,0000,0000,,-2 x 7 + g(1)가 됩니다
Dialogue: 0,0:01:02.95,0:01:07.21,Default,,0000,0000,0000,,g(1) 은 -5 니까
Dialogue: 0,0:01:07.21,0:01:11.84,Default,,0000,0000,0000,,-2 x 7 + (-5) 입니다
Dialogue: 0,0:01:11.84,0:01:20.30,Default,,0000,0000,0000,,이것은 -14 - 5 = -19 로 간단히 됩니다
