Find the value of 𝑓 of square root two given the function 𝑓 of 𝑥 equals 𝑥 squared plus square root two 𝑥.
00:00:11.200 --> 00:00:20.600
So in order to find the value of 𝑓 of square root two, we need to plug in square root two for 𝑥.
00:00:21.240 --> 00:00:28.840
So we are replacing the 𝑥s with square root two, and now we evaluate.
00:00:30.080 --> 00:00:44.880
Square root two squared is two, and square root two times square root two is also two, and two plus two equals four.
