To graph an equation as given:
[tex]f(x)=\lvert x\rvert[/tex]
The absolute value of a number (positive or negative) is always the positive number:
[tex]\lvert\pm a\rvert=a[/tex]
Give values to x and calculate the corresponding value of f(x) or y
x= -4
[tex]f(-4)=\lvert-4\rvert=4[/tex]
x= -2
[tex]f(-2)=\lvert-2\rvert=2[/tex]
x=0
[tex]f(0)=\lvert0\rvert=0[/tex]
x= 2
[tex]f(2)=\lvert2\rvert=2[/tex]
x= 4
[tex]f(4)=\lvert4\rvert=4[/tex]
Use the next points to grpah the equation: (x,y)
(-4,4) (-2, 2) (0, 0) (2, 2) (4 , 4)
Graph of the equation:
