Answer:
{2,3,4,5}
Step-by-step explanation:
Domain is the set of x-values for which the function is defined.
Range is the set of y-values for which the function is defined (set of values corresponding to the set of x-values).
The function is given as 
The domain is (-2,0,2,4)
That means, we need to plug-in the 4 numbers given into x of the function and find the 4 corresponding y values (the range).
So, lets do this:
putting x = -2,
putting x = 0
y = 3
putting x = 2
putting x= 4
Thus, the range is {2,3,4,5}
Answer:
Here we need to solve:
The sum of the fractions is equal to the quotient between the fractions.
Notice that the two values:
y = 3
y = -3
make the denominator equal to zero, so those values are restricted.
We can simplify the right side to get:
Now we can multiply both sides by (y - 3)
Now we can multiply both sides by (y + 3)
First, let's see the determinant of that quadratic equation:
We can see that it is negative, thus, there are no real solutions of the equation.
Thus, there is no value of y such that the origina equation is true,
Answer:
-5
Step-by-step explanation:
do it chronologically so
7-3=4
4-10= -6
-6+9= 3
3-8= -5
Answer:
Third choice is correct
Step-by-step explanation:
-2x-y=-2
-y=2x-2
y=-2x+2
3x-y=-2
-y=-3x-2
y=3x+2
These two lines intersect at (0, 2)
