So for this problem, we are defining a function that exists in r3 with three variables.
00:07
So it is g, x of y of z, is equal to x cubed, y squared, z times the square root of 10 minus x minus y minus z.
00:26
So the first thing that we want to do is evaluate it at the point one, two, three.
00:32
So g of one, two, three is equal to one cube, which is one times two squared, which is four, times four, times z, which is three.
00:46
And the next thing is evaluate the square root on the inside.
00:51
So it's minus three, minus one, minus two, minus three, is minus six.
00:55
So it's ten minus six...
