I really need someone to help me out

Mathematics
1 answer:
elixir [45]3 years ago
3 0

All it takes for a relation to be a function is for each possible first number of a pair there's only one possible second number.


So if any of the sets has two pairs with the same first number, that one's not a function.


The last one has (3,2) and (3,5) so isn't a function.

Write the equality for the graph
Veronika [31]

≥ the graph would be going to your right

≤ the graph would be going to your left

Both cases assume x is on the left side of the inequality.

If the circle is open < or > will be used.

If the circle is shaded in then use ≤ or ≥

If the circle is open, then x<2 would indicate that the ray is going left (which it is) and 2 is not included.

Answer: x < 2

Rainbow [258]

Answer:

y = - 4x

Step-by-step explanation:

Here, it is given that the slope of a line is - 4 and the y-intercept is 0.

Now, if the slope of a straight line is m and the y-axis intercept is c, the by slope-intercept form the equation of the straight line is given as  

y = mx + c ......... (1)

Therefore, in our case m = - 4 and c = 0 and using equation (1), the equation of the given straight line is
