Hi.
00:02
So we are to evaluate the function at the given values of the independent variables.
00:07
For a, x is 0, and y is 0.
00:12
So plug in the values of x and y in 5 minus x squared, x is 0.
00:19
So replace that with 0 squared minus 5 and y is also 0.
00:24
So why write 0 in y raise that to the power of 2.
00:28
So this is 0 and this is 0 as well.
00:34
So the answer for letter a is 5.
00:40
When x is 0, y is 1.
00:42
So we have 5 minus 0 squared minus 5 times 1 squared.
00:49
That's 5 minus 0 minus 5.
00:53
This would give us 0.
00:55
So that's the answer for letter b.
00:58
Next, x is 2.
01:01
Y is 3.
01:01
So 5 minus x squared minus 5 multiplied by 3 based to the power of 2...
