f(x)=2(x+2)^2(x+4)^2

**Reiny**, Tuesday, November 20, 2007 at 11:05pmvisualize the function as

f(x) = 2(x+2)(x+2)(x+4)(x+4)

which would make it a fourth degree function.

Fourth degree functions tend to look like a "W" in their general form, anyway they "rise" into the first and second quadrants.

notice there are double roots at x=-2 and x=-4, so the curve 'touches' the x-axis at -2 and -4 without crossing

What does it do between -2 and -4?

Try x=-3, f(-3) = 2

try f(0), you get f(0) = 128

Can you see the "W" ?
