Behavior Of A Piecewise Function
Consider the following piecewise function:
f(x) = x2 + 5 if x ≥ 5
f(x) = x + 5 if 5 > x > 0
f(x) = x - 5 if -5 < x < 0
f(x) = x2 - 5 if x ≤ -5
At x = -2, the graph of the function:
A
slopes upward and to the right.
B
has a range of all real numbers.
C
consists of four straight lines arranged like a stair step.
D
is linear and downward-sloping.
