Which of the following relations is a function?

Mathematics
1 answer:
Dominik [7]4 years ago
6 0

Answer:

A

Step-by-step explanation:

It would be "a" because the x points are all different, as seen on the others they all have at least one similar x.

Answers:

  • first box = 1
  • second box = 1
  • third box = 3
  • fourth box = 3

Refer to the graph below.

==========================================================

Explanation:

If f(x) is an even function, then f(-x) = f(x) for all x in the domain.

What this means is that we have symmetry about the y axis. We can reflect that given curve over the y axis to generate the missing left side.

The graph shows that (1,1) is on the orange curve. It reflects over to (-1,1). This means 1 goes in the first box.

Use the rule (x,y)  \to (-x,y) to apply a y axis reflection. We simply just change the sign of the x coordinate from positive to negative, while keeping the y coordinate the same.

---------------

We can also see that (3,1) is also on the orange curve. It reflects over to (-3, 1) using that rule mentioned earlier.

1 goes in the second box

---------------

The graph your teacher gave you shows that if we plugged in x = 5, then we get y = 3. In other words, the point (5,3) is on the orange graph.

It reflects over to (-5, 3) to show that x = -5 leads to the output y = 3

3 goes in the third box

----------------

Lastly, the point (6,3) reflects to (-6,3) when reflecting over the y axis.

3 goes in the fourth box.

See the graph below.

trapecia [35]

Answer:

<em>75.6</em>

Step-by-step explanation:

100% - 73% = 27%  

27% = 0.27

280 × 0.27 = <em>75.6</em>

I'm stuck. Can anyone help please?
Serjik [45]

log₉(<em>x</em> - 7) + log₉(<em>x</em> - 7) = 1

2 log₉(<em>x</em> - 7) = 1

log₉(<em>x</em> - 7) = 1/2

Take the base-9 antilogarithm of both sides; in other words, make both sides powers of 9:

9^{\log_9(x-7)} = 9^{1/2}

9^{1/2} can also be written as √9 = 3, and b^{\log_b(a)}=a, so the equation reduces to

<em>x</em> - 7 = 3

Solve for <em>x</em> :

<em>x</em> = 10

Based on the graph below, how would you describe the curve?
Vinil7 [7]

The best description of the curve of the given graph is called; A: Many to One Function

<h3>How to interpret function graphs?</h3>

A function is a relation in which each element is mapped to a single element i.e. no element is mapped to two different elements.

The given graph passes the vertical line test and as such we can say it is a function.

Also, the graph of a linear function is a straight line but the graph we are given is not a straight line and as such it is not a linear function.

Lastly, the graph does not passes the horizontal line test because between the interval from -1 to 0, the same value y-output is obtained many times and hence it is not a one-to-one function but a many to one function.
