The graphs of functions f, g are given.
(a)Find the values of "f(-4)" and "f(3)."
(b) What value of "x" has "f(x)=g(x)" ?
"x_2=3, f(3)=1=g(3)"
"x_3=4, f(4)=0=g(4)"
(c) Find the approximate solution of the equation "f(x)=-1"
(d) In what interval does "f" decrease?
"f" decreases for "x\\in (-\\infin,-2)\\cup(2,\\infin)"
(e) Find the determinable range of the function f and the range of values.
