Question

What is the Y intercept? and where is the function positive?where is it negative?

Answer 1

y=2

$\lbrack0,1)\text{ }\cup\text{ (3,4}\rbrack$

$\begin{gathered} so,\text{ the function is negative in } \\ (1,3) \end{gathered}$

Explanation

Step 1

The y -intercept of a graph is the point where the graph crosses the y -axis.

so , let's check the graph

therefore, the y-intercept is 2

Step 2

The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero)

hence, the function is potive in ( in x axis)

$\lbrack0,1)\text{ }\cup\text{ (3,4}\rbrack$

Step 3

negative region

The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

$\begin{gathered} so,\text{ the function is negative in } \\ (1,3) \end{gathered}$

I hope this helps you
