Question #236695

Graph the piecewise function below

h(x) = { y= 3x + 2 if -2 < x < 1

y= 1/2x - 1 if x < -2

What is domain? (Interval notation)

What is range? (Interval notation)

Expert's answer

"h(x) = \\begin{cases}\n y= 3x + 2 &\\text{if } -2 < x < 1 \\\\\n y= \\frac{1}{2}x - 1 &\\text{if } x < -2\n\\end{cases}\\\\"

Now, domain for the given function isÂ "x\\in"Â "(-\\infty,-2)\\cup(-2,1)" [From graph]

At "x=1," we get "y=5"

Range isÂ "(-\\infty,-4)\\cup(-4,-2)\\cup(-2,5)"
