Answer:
x≠-3 or x<-3 and -3<x or (∞,-3) and (-3,∞)
Step-by-step explanation:
If the expression you have given is then the domain is x≠-3
This is because in a function that is a fraction the denominator can never equal 0, otherwise you are dividing by 0 which is undefined.
Here the denominator is x+3 and so to find the undefined value of x:
Set x+3 equal to 0:
x+3=0
Subtract 3:
⇒ x=-3
That value is undefined since it results in the division of 0 which also means that it is not in the domain.
Answer:
y=-5x-5
Step-by-step explanation:
The line contains points at (-2,5) and (0,-5)
(y1-y2) / (x1-x2) = slope
(-2,5) =(x1,y1)
(0,-5) = (x2,y2)
(5--5) / (-2-0)
10 / -2 = -5
y= -5x + b
plug in points for x and y to find b
5=-5(-2)+b
5=10+b
-5=b
y=-5x-5
