Answer:

It's fine. It is a function. The language can be very convoluted. Put simply a domain value cannot have 2 different range values.

Step-by-step explanation:

The confusing part I think, is probably the fact that -1 and 1 both have an answer of 5.

That's fine. Parabolas do that and they are functions. Two different xs can have the same value. The thing that eliminates functions is when the x value (the domain) has two different y values (the range values). Then you don't have a function.

To try and make it clearer if 1 pointed at both 3 and 5 you would not have a function.

What is the value of x? –2x – x + 3 = –12

Degger [83]

Answer:

x = 5

Step-by-step explanation:

-2 -1(coeffcient of -x) = -3

-3x +3 =-12

subtract 3 (the constant) from both sides

cancelling it on the left and leaving -3x = -15

divide each side by -3 leaving x and 5

x = 5

Given: line a is parallel to line b. Identify a pair of congruent corresponding angles.

UNO [17]

Answer:

Option

D . 4 & 8

Step-by-step explanation:

we know that

When two lines are crossed by another line (which is called the transversal), the angles in matching corners are called corresponding angles. If the two lines are parallel, the corresponding angles are congruent.

In this problem, the two lines are parallel

therefore

$m\angle 1=m\angle 5$ ----> by corresponding angles
