Question

Which graph represents the piecewise-defined function?

y=⎧⎩⎨⎪⎪−4   if  x≤−30   if  x=23   if  x>2

Answer 1

it can be a pain when nobody helps... ur top right is correct

Explanation:

Answer 2

B

Explanation:

A Piecewise function, is a function whose main feature is to be defined by a sequence of intervals. In these graphs we have:

`f(x)=y=\left\{\begin{matrix}-4&&if\: x\leqslant -3\\ 0&&if\: x=2\\3&&if\: x>2\end{matrix}\right.`

So we have three intervals

x=2, for y=0

x >2, for y=3

x ≤ -3, for y=-4

The Piecewise function is putting together these intervals in the coordinate plane. So, it's B.
