My math homework tells me to come up with 4 points to this piecewise function
f(x)= {-x, if x<1
{x+1, if x >or= 1
Could someone tell me how I coudl come up with these 4 points. Thanks!!!!!!
Hello,
if you want to calculate the coordinates of points choose a x-value and plug it into the equation.
For instance:
x = -2 ==> A(-2, 2) You have to use the first term because the x-value is smaller than 1
x = 0 ==> B(0, 0) You have to use the first term because the x-value is smaller than 1
x = 1 ==> C(1, 2) You have to use the second term because the x-value equals 1
x = 3 ==> D(3, 4) You have to use the second term because the x-value is greater than 1
I've attached an image of the graph.
