Question
Consider the graph of the piecewise function y = f(x) pictured below. (a) State the value of f(1). (b) State the domain of the piecewise function. (c) State the range of the piecewise function. (d) State the x-intercept(s), if any. (e) State the y-intercept(s), if any. (f) State the interval(s) on which the function is increasing. That is, for what x-values is the function increasing? (g) State the interval(s) on which the function is decreasing. That is, for what x-values is the function decreasing?Explanation / Answer
a) f(1) = 4
b) Domain : [ -5 , 5]
c) Range : [ -3 , 4]
d) x intercepts : x = -4 , 3
e) y intercept : y = 3
f) increasing : [ -5 , 1] U [ 4 , 5]
g) decreasing : [1 , 4]
