pdf of piecewise function

Its also in the name: piece. Since the graph covers all values of x, the domain would be all real numbers or (-, ). In the function above, we can see that f(x) is a piecewise function since it is defined differently for the three intervals x> 0, x = 0, and x <0.We can interpret piecewise functions by looking at the different given intervals. $ "b@\~ "A3d-He`$x@ A piecewise-defined function is one that is described not by a one (single) equation, but by two or more. << hb```f``2f`a`fc@ >r,`h$R4;AY{a```Jp10\ylJ4/M(p8EH#w1A p) ^fq&/co=( A`Sd *Mlr gHu;CG3CXId:x+DKD$I/ZQcXD#M;"Ip, O(a3GDn_M - Since the graph only covers the values of y above the x-axis, the range of the function is [0, ) in interval notation. We can create functions that behave differently based on the input (x) value. The first step is to show this is a valid pdf.

Let's see how it would appear without the limitation: When Adding Restrictions in the if Statements. y4yi;ch;vHbyT4R&:RK=yi@Q0 gq:\k3! x[)|a5X-"#u29\b\ v]-N;k1K&PA;X] (Vh0gtBBM> E+4tD=G6[Cr16P1w= }1!s&kbKhC`WjR_?RJSk?P$kfvq5%06q S=!Pb/ &/ 2[Q>A 2IHeTXw=0'9P5Hy9 KHLDK P3U[KCIeRAwHpi:LC0_BB`^dWpX73*yl>U6(LZ[G|v{Wg^MfUNm;LjZtD $v4 \[\left\{\begin{matrix} y = x^{2} \text{ if x < 0} \\ y = x + 2 \text{ if 0 }\leq x \leq 3 \\ y = 4 \text{ if x }> 3\end{matrix}\right.\]. Evaluate the given piecewise function at the given values of x as shown below. Carefully graph each of the following. This also means that f(-6) = -2(-6) = 12 and f(0) = 1.
