Question

For each piecewise function, find the specified function values.
g(x)={x+4, for x<1
{8-x, for x>1
g(-4),g(0),g(1), and g(3)

Answer 1

What does the "{" mean in g(x)={x+4 and {8-x ?

It looks like g(1)is undefined.

Answer 2

as noted by drwls, one of your inequality signs should have been ≥ or ≤
As it stands, for x=1 the function is not defined.

when x = -4 or 0 use g(x) = x+4
when x = 3 use g(x) = 8-x

Answer 3

For the piecewise function, find the values g(-8), 8(3), and g(8).

g(x)={X+6,FOR X<=3
7-x, for x>3
