In this problem, we will cover how to interpret a numerical example of a two -variable function.
00:09
The two -variable function in this case is body mass index.
00:17
So the body mass index depends on two variables, the first of which being height in inches, as represented by the letter h, and the second being weight in pounds, as represented by the litter, so we see six values of height going down the left -hand side of the table and five values of weight going across the top of the table.
00:48
And each resulting body mass index from every combination of height and weight is recorded in the table.
00:58
Now, say we have two restrictions.
01:03
Okay, the first being which that height is restricted.
01:06
To 6 feet.
01:09
Six feet translates to 72 inches, so i'm just going to highlight 72.
01:17
If weight is not being restricted, that means all of the vmi values in the corresponding row are what we're going to focus on.
01:30
So we're going to write these values down in this table right here.
01:37
So 16 .3, 19 .0, 21 .7, 24 .4, and 27 .1...
