Question

Which point lies on the graph of the following piecewise function?
y = x - 1 if x < 2
y = x2 if x greater than or equal to 2

Answer 1

(-1, 1)
(1, 1)
(2, 1)
(3, 9)

Answer 2

This is the graph

Answer 3

I know that the open circles mean that it is less than the number
and the open circles are equal to or to the number

Answer 4

So (3,9) by counting the rise over run?

Answer 5

Look at the given function
```
y = x - 1 if x < 2
y = x^2 if x greater than or equal to 2
```

Answer 6

try each option,
the first option is (-1, 1)

since the x value, -1 is less than 2, you need to use first case for working y :
y = -1-1 = -2
so (-1, -2) is a point on the graph, not (-1, 1)

Answer 7

ok, I get that

Answer 8

So I did the diagram, so why can't 2,1 be a possible point? @ganeshie8

Answer 9

thanks sir ganeshie i had almost the same problem
