4. Add the third piece of the function to
Y1
. This piece is
f(x)=6
ì
x for x≥5. It is entered as
(6
ì
x) (x
≥
5)
. When x is
greater than or equal to 5, the test (x≥5) returns 1. The
third piece of the function is then equivalent to (6
ì
x)×1.
When X is less than 5, the test (x≥5) returns 0. The third
piece of the function is then equivalent to (6
ì
x)×0.
