What is the domain of the function y=x-1 ​
Amiraneli [1.4K]

Answer:

All rational numbers or all numbers

Step-by-step explanation:

The function is a linear positive slope equation, which looks like the screenie below. Lines always travel forever, and since it is a linear line with a slope, it will be forever going in both directions.

Domain is the x-values that a function has, while range is the y-values.

Since the domain and range are infinite, it is all real numbers.

Hope this helps!

I zoomed out 2 million units out so you get what im saying kinda

Determine whether the vectors u and v are parallel, orthogonal, or neither. u = <6, -2>, v = <8, 24>
ratelena [41]
We'll check if they're orthogonal:
u*v=0
(6,-2)*(8,24)=0
6*8+(-2)*24=0
48-48=0
0=0
they are orthogonal vectors

Y= -1/2x-3 <br> Plot the x- and y-intercepts to graph the equation.
viva [34]

Answer:

Graph is attached below

Step-by-step explanation:

Intercepts are values of x and y at which the graph of the function intersects coordinate axis.

Given equation,

y=-\frac{1}{2}x - 3

For x-intercept,

y = 0,

\implies 0 =-\frac{1}{2}x - 3

3 =-\frac{1}{2}x

\implies x =-6

Thus, x-intercept is at (-6, 0)  

For y-intercept,

x = 0,

\implies y =-\frac{1}{2}(0) - 3=-3

Thus, y-intercept is at  (0, -3)

Now, join these two points to show the line in coordinate plane.
