Answer: -3, 3.5
Step-by-step explanation:
This is because the X axis goes first.
Answer:
The range is:
{-4, 1, 2, 5, 8}
Step-by-step explanation:
Given the function

- We know that the domain of a function is the set of input or argument values for which the function is real and defined.
As the domain interval -2 ≤ x ≤ 2
i.e. the values in the domain = {-2, -1, 0, 1, 2}
- We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
As the domain interval -2 ≤ x ≤ 2
Putting all the x-values in the domain interval in the function
so
putting x=-2 in the function


putting x=-1 in the function


putting x=0 in the function


putting x=1 in the function


putting x=2 in the function


Thus, when we put the domain values, the corresponding range values are:
x y
-2 -4
-1 1
0 2
1 5
2 8
Therefore, the range is:
{-4, 1, 2, 5, 8}
Expand the brackets:
5y + 50 = 40
minus 50 on both sides to get 5y alone
5y = -10
divide both sides by 5 to find y
y= -2
∴ 1/4y = -0.5
7(4 + 5) = 63
28 + 35 fits the criteria for your question.
