WILL GIVE BRAINLIEST ‼️ The graph represents the piecewise function:

Step-by-step explanation:

You can find the first function if you know the general form of a line:

where is the slope and the intercept point with the -axis.

So in the first case the slope is 1 because the next formula

And you can find the interception point if extend the line, then in our case is  3.

So the function is:

In the other case is constant function that's mean that the function has the next form

Where is a constant.

So you only have to observe what is the value for each point in the interval, in this occasion is 5.

So the final answer is:

current in the circuit at time t is /, then the power delivered to the resistor is
