Let the age of Jay be x years, so age of Jay's father is 2x years .

After 20 years,

Jay's age will be (x+20)years

And Jay's father age will be (2x+20) years

But at that time, jay's  age will be

\frac{2}{3} (2x+20) years

So we have

x+20 = \frac{2}{3} (2x+20)

Cross multiplication

3(x+20) = 2(2x+20)
\\
3x+60 = 4x + 40
\\
60-40 = 4x-3x
\\
x=20 years

Therefore Jay's age is 20 years and Jay's Father's age is 40 years .

Is this graph a function or not a function?
weeeeeb [17]

Answer:

It is a function.

Step-by-step explanation:

You can test if a graph is a function if you draw a vertical line anywhere on the graph and you see it hits two points.

This is the table for the graph.

\left[\begin{array}{ccc}x&y\\-3&0\\0&1\\3&2\end{array}\right]

Remember these rules:

  • Each x value, or input, has its unique y value, or output
  • If you draw a vertical line anywhere on the graph, it should only go through one point

We can check these two rules for this graph:

  • Does each x value have its own, unique y value? Yes
  • If you draw a vertical line anywhere on the graph, does it only go through one point? Yes, there are no overlaps

Keep in mind that two different x-values can have the same y value.

Figure 1:

It has two x values with the same y-values.

Figure 2 and 3:

The vertical line goes through two points. So the same x-value has two different y-values.
