Answer:
Step-by-step explanation:
No...this is not a function.
A function will not have ANY repeating x values.....they can have repeating y values, just not the x ones.
And this set of numbers has repeating x values of 1
in other words, in a function, all the x values have to be different numbers....none can be the same
Answer: The domain of f(x) is all real numbers,
and range of f(x) is
.
Explanation:
The given function is,

The domain is the set of all possible values for which the value of function exist.
The given function is defined for any real value of x, therefore the domain of the function is set of all real number. it can be written in interval notation
.
The range is the set of possible value of f(x) at different value of x. Range is the set of outputs.
In the given function,

for any value of x.
So,


Therefore the value of f(x) is always greater than 2 and the range of the function is
.
Hello from MrBillDoesMath!
Answer:
Rule: Y = 5x - 3
Table Line 4: Y (output) = 37
Table Line 5: X (input) = 10
Discussion:
This one had MrBill going for a while! The rule appears to be
Y = 5 * x - 3
Check it out! Substitute some table values (input) and check the (output) values.
Table line 4: Y(8) = 5 * 8 - 3 = 40 - 3 = 37 (Output)
Table line 5: If Y = 47 = 5*x -3 => add 3 to both sides
47 + 3= 5x => as 47 +3 = 50
50 = 5x => divide both sides by 5
x = 50/5 = 10 (input)
Thank you,
