The piece-wise function is defined by:

$f(x) = 1, -3 \leq x < -1$

$f(x) = 2, -1 \leq x < 1$

$f(x) = 3, 1 \leq x < 3$

A piece-wise function is a function that has different definitions, based on the input.

In this graph:

When x is between -3(inclusive, closed circle) and -1(exclusive, open circle), the value is 1, thus, the first definition is:

$f(x) = 1, -3 \leq x < -1$

When x is between -1(inclusive) and 1(exclusive), the value is 2, thus, the second definition is:

$f(x) = 2, -1 \leq x < 1$

When x is between 1(inclusive) and 3(exclusive), the value is 3, thus, the third definition is:

$f(x) = 3, 1 \leq x < 3$

Final answer:

A piecewise function is defined by multiple sub-functions, each applying to a certain interval of the main function's domain. An example might be ' -3 is equal to x <-1', representing a portion of the function where any x-value less than -1 outputs -3.

Explanation:

Without the piecewise function graph, it's difficult to identify the correct algebraic definition. However, a piecewise function is a function which is defined by multiple sub functions. Each sub function applies to a certain interval of the main function's domain, which is why we see conditions like 'x < -1' following the function.

For instance, if we look at option C ' -3 is equal to x <-1', it suggests there is a piece of the function where any x-value less than -1 will output -3. It is important to note that these piecewise functions are visualized on a graph, often appearing as lines or curves that start or stop at certain points.

If y=2x-3 were changed to y=2x+5 , how would the graph of new function compare with the original?

Answers

The new graph would have the same slope (2) as the original one,
but its y-intercept would be [ 5 - (-3) ] = 8 higher.

The new straight line would be parallel to the original straight line,
and they would be 8 units apart everywhere.

Answer: it would be shifted up
