hich set of points represents a function? A. (0, 2), (1, 2), (2, 4), (3, 5), (4, 5) B. (1, 2), (2, 1), (2, 4), (3, 5), (4, 5) C.

Set A. (0, 2), (1, 2), (2, 4), (3, 5), (4, 5) represents a function
Why?
A function is a special kind of relation in which <u>each value of the input variable is paired with </u><u>exactly one</u><u> value of the output variable.</u>
Each value in the input variable in set A is paired with exactly one value of the output variable.
0 - 2
1 - 2
2 - 4
3 and 4 - 5
While on the other hand, sets B, C and D has the values of the input variable paired with more than one value of the output variables.
Answer:
Y = 1/4x + 1/2
Step-by-step explanation:
The inverse is found by reflecting the graph across the y=x line. In the equation, this result by switching x and y then solving for y.
Y =4x-2
X=4y-2
X+2=4y
(X+2)/4= y
1/4x +1/2 =y

Answer: x = -3
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
y = -3x + 1
Step-by-step explanation:
Plug in your x (2) and y (-5) values into your slope-intercept formula (y=mx+b).
-5 = -3(2) +b
Solve for b:
-5 = -3(2) + b
-5 = -6 + b
1 = b
Plug in the value of <em>b, </em>and<em> </em>the slope (-3) for the formula:
y = -3x + 1
