Math Problem Statement

what is the y equation of f(x)=abs(x+3)-2

Solution

The function given is f(x)=x+32f(x) = |x + 3| - 2. To express this function without the absolute value, we consider two cases based on the expression inside the absolute value:

Case 1: x+30x + 3 \geq 0 (i.e., x3x \geq -3)

In this case, x+3=x+3|x + 3| = x + 3, so the function becomes: f(x)=(x+3)2=x+1f(x) = (x + 3) - 2 = x + 1 Thus, for x3x \geq -3, f(x)=x+1f(x) = x + 1.

Case 2: x+3<0x + 3 < 0 (i.e., x<3x < -3)

In this case, x+3=(x+3)=x3|x + 3| = -(x + 3) = -x - 3, so the function becomes: f(x)=(x3)2=x5f(x) = (-x - 3) - 2 = -x - 5 Thus, for x<3x < -3, f(x)=x5f(x) = -x - 5.

Summary

The piecewise function is:

\begin{cases} x + 1 & \text{if } x \geq -3, \\ -x - 5 & \text{if } x < -3. \end{cases}$$ Would you like further details or clarification on this? Here are 5 related questions you might find interesting: 1. How do you graph a piecewise function like this one? 2. What is the vertex of the function $$f(x) = |x + 3| - 2$$ and how is it determined? 3. How do you determine the range of $$f(x) = |x + 3| - 2$$? 4. What happens to the graph of $$|x|$$ when you add or subtract a constant inside the absolute value? 5. How do transformations affect the graph of a function like $$f(x) = |x|$$? **Tip:** When dealing with absolute value functions, always consider breaking down the problem into cases where the expression inside the absolute value is positive or negative.
