The piecewise function h(x) is shown on the graph. On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 3, negative 7) and goes up to an open circle at (1, 1). The second line has a closed circle at (1, negative 1) and goes down to an open circle at (2, negative 3). What is the value of x when h(x) = −3?

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
