Use a graphing calculator to graph the function using the given viewing window. Use the graph to decide if the function is one-to-one. If the function is one-to-one, give the equation of the inverse function.f(x) = x4 - 6x2 + 5; [-3, 3] by [-40, 40]
A. one-to-one; f-1(x) = 
B. one-to-one; f-1(x) = 
C. one-to-one; f-1(x) =
+ 6x2
D. not one-to-one
Graph the function by starting with the graph of the basic function and then using the techniques of shifting, compressing, stretching, and/or reflecting.f(x) = (x + 4)3 + 7
