Describe the surface in double-struck r3 represented by the equation x + y = 3. this is the set {(x, y, 3 − x − y)|x is in doubl
e-struck r, y is in double-struck r} which is a vertical plane that intersects the xy-plane in the line y = 3 − x, z = 0.
1 answer:
First, note that <span>x+y=3</span><span> is a linear in </span>x<span> and </span>y<span>, and independent of </span>z<span>. So, this is just a line in the </span><span>xy</span>-plane, extended into and out of the plane. Since we have the line, we have all the points we need; <span>
</span>the equation in R3 is a plane<span> parallel to the z-axis and contains the line
y = 3 - x </span>
The plan sketched below.

=
=
= - 3.5
=
=
=
= - 7
Thus coordinates of R = (- 3.5, - 7 )
Answer : y>0
f(x) = 9*2^x
f(x) is an exponential function
When we plug in positive value for x , the value of y is positive
When we plug in negative value for x , the value y is also positive
So for any value of x, the y value is positive always.
Range is the set of y values for which the function is defined
y values are positive , so range is y >0
