I have to find:
g(1)=
and
g(5)=
I have drawn the graph and I am a little unsure where to go from there. I know area is involved somehow but not entirely sure what to do. Any help is appreciated

Yep. (Nod)Emma_011 said:Based on what is given, the area would be 20 between x=-5 and x=0 and the area between x=0 and x=1 would be 5.
So it would be 20-5=15
No, only the part to the right of x=4 is zero.Emma_011 said:Since there is no area to add or subtract would it just be 0?
A piecewise function is a mathematical function that is defined by different equations on different intervals. This means that the function may have different rules or formulas for different parts of its domain.
To integrate a piecewise function, you first need to find the integral for each piece of the function separately. Then, you can combine the integrals using the appropriate limits of integration for each piece.
Piecewise functions allow for more flexibility in representing real-world situations that may have different rules or behaviors in different scenarios. They also make it easier to work with complex functions by breaking them down into smaller, more manageable pieces.
Yes, piecewise functions can be used in a variety of mathematical problems, including calculus, algebra, and geometry. They are particularly useful in problems involving optimization, modeling, and real-world applications.
One common mistake when integrating a piecewise function is forgetting to change the limits of integration for each piece. It is important to make sure that the limits match the interval for each piece of the function. Additionally, it is important to check for continuity at the points where the pieces of the function meet to ensure a smooth and accurate integration.
