State the power and constant of variation for the function, and then analyze it.f(x) = -7x4
What will be an ideal response?
Power is 4; constant of variation is -7; Domain: all reals; Range: (-?, 0] ; Continuous; Increasing on (-?, 0), Decreasing on (0, ?); Symmetric with respect to the y-axis (an even function); Bounded above but not below;
Local maximum at x = 0; No asymptotes;
End behavior: 
(-7x4) = -? and 
(-7x4) = -?.
