The domain of a function is the complete set of possible values of the independent variable.
In plain English, this definition means:
The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
So for Graph 1 the domain is : (-∞,∞)
domain for graph 2 is : [-1,5]
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
In plain English, the definition means:
The range is the resulting y-values we get after substituting all the possible x-values.
So range for graph 1 is (-∞,∞)
range for graph 2 is [-1,2]
Answer:
x=2
y=3
z=0

Answer:
60m - 36
Step-by-step explanation:
<em>This equation is asking you what is this quantity times 12? So you distribute the 12 (multiply everything in the quantity by 12)/</em>
(5m - 3)12
12 x 5m = 60m
12 x (-3) = -36
60m - 36
Answer:
The error was that -10+(-10) does not equal 0.
-10+(-10) = -10-10 = -20
