Answer:
C. (1, -3)
Step-by-step explanation:
Plug in the x to get the y in the equation. The point must fit the formula.
Plug in C. (1, -3), in which x = 1, y = -3:
(-3) = 2(1) - 5
Simplify:
(-3) = 2(1) - 5
-3 = 2 - 5
-3 = -3 (True).
C is your answer.

Answer:
False
Step-by-step explanation:
4g + 7 = 5g - 1 - g
Simplify:
4g + 7 = 4g - 1
Subtract both sides by 4g:
7 = -1
There are no solutions to this equation.
Answer:
It is a function
Step-by-step explanation:
A function is of the form:
Where each of the x values must be distinct.
The x values are referred to as domain while the y values are called range.
Having said that, the given data can be represented as follows:
-----------
<em>From the representation above, none of the x values are repeated.</em>
<em>Hence, it is a function</em>
