In this problem of functions of several variables, we have to match the equation with one of the graphs below.
00:08
So here are the graphs i'm showing you.
00:12
So here are the graphs a, b, c, d, e, f, g and h.
00:17
And now we have given the equation or we can see the function, say f of xy is equals to 1 minus 3x plus 2y.
00:28
So now as you can see this function is a linear function so here this is a linear function in x and y so this would represent a plane in three axis coordinate geometry so we have to search for plane so we have plane g and h now what do you have to do we have to put for finding the x say we can say for finding the x intercept so x intercept so x intercept so put y and z term is equal to 0.
01:05
So we have z is equal to 1 minus 3x plus 2y.
01:10
So this term put 0 and this term also we have to put 0.
01:14
So we have 1 minus 3x is equal to 0.
01:17
That means x is equals to 1 divide with 3.
01:20
So this is the x intercept...
