Dialogue: 0,0:00:06.60,0:00:08.46,Default,,0000,0000,0000,,And they've defined,\Nat least graphically, Dialogue: 0,0:00:08.46,0:00:10.76,Default,,0000,0000,0000,,f of x and g of x here below. Dialogue: 0,0:00:10.76,0:00:12.34,Default,,0000,0000,0000,,So let's see how we\Ncan evaluate this. Dialogue: 0,0:00:12.34,0:00:14.27,Default,,0000,0000,0000,,Well, to do this, we\Nfirst have to figure out Dialogue: 0,0:00:14.27,0:00:16.54,Default,,0000,0000,0000,,what f of negative 6 is. Dialogue: 0,0:00:16.54,0:00:19.76,Default,,0000,0000,0000,,So our input into our\Nfunction is negative 6. Dialogue: 0,0:00:19.76,0:00:22.42,Default,,0000,0000,0000,,And we'll assume that's\Nalong the horizontal axis. Dialogue: 0,0:00:22.42,0:00:24.11,Default,,0000,0000,0000,,So our input is negative 6. Dialogue: 0,0:00:24.11,0:00:28.69,Default,,0000,0000,0000,,And based on our function\Ndefinition, f of negative 6 Dialogue: 0,0:00:28.69,0:00:30.01,Default,,0000,0000,0000,,is 7. Dialogue: 0,0:00:30.01,0:00:30.89,Default,,0000,0000,0000,,So this thing. Dialogue: 0,0:00:30.89,0:00:35.69,Default,,0000,0000,0000,,Let me write this down. f\Nof negative 6 is equal to 7. Dialogue: 0,0:00:35.69,0:00:36.97,Default,,0000,0000,0000,,And what is g of 1? Dialogue: 0,0:00:39.91,0:00:42.89,Default,,0000,0000,0000,,Well, once again,\Nhere's our input axis. Dialogue: 0,0:00:42.89,0:00:45.41,Default,,0000,0000,0000,,And then the function\Nsays that g of 1, Dialogue: 0,0:00:45.41,0:00:48.66,Default,,0000,0000,0000,,which is right over\Nthere, is negative 5. Dialogue: 0,0:00:48.66,0:00:51.92,Default,,0000,0000,0000,,g of 1 is equal to negative 5. Dialogue: 0,0:00:51.92,0:00:57.24,Default,,0000,0000,0000,,So this statement simplifies\Nto negative 2 times Dialogue: 0,0:00:57.24,0:00:59.70,Default,,0000,0000,0000,,f of negative 6, which is 7. Dialogue: 0,0:00:59.70,0:01:07.26,Default,,0000,0000,0000,,So times 7 plus g of\N1, which is negative 5. Dialogue: 0,0:01:07.26,0:01:12.58,Default,,0000,0000,0000,,So plus negative 5, which\Nsimplifies to-- let's see. Dialogue: 0,0:01:12.58,0:01:17.90,Default,,0000,0000,0000,,Negative 2 times 7 is\Nnegative 14 plus negative 5, Dialogue: 0,0:01:17.90,0:01:20.20,Default,,0000,0000,0000,,which is negative 19. Dialogue: 0,0:01:20.20,0:01:22.66,Default,,0000,0000,0000,,And we are done.
