g(x)=-1/5x + 2

I got 0

How do I graph f(x)=x^5-4x^3-12x

**Reiny**, Tuesday, October 23, 2007 at 11:09pmyour first one is right

for f(x)=x^5-4x^3-12x

=x(x^4 - 4x^2 - 12)

=x(x^2-6)(x^2+2)

if this had been the equation

x^5-4x^3-12x = 0

there would be solutions of

x=0, x=±√6 = ±2.45, and 2 complex roots

so the graph crosses at -2.45, 0, 2,45

it rises into the first quadrant, and drops into the third quadrants.

The two complex roots cause a "wiggle" in the first quadrant above the x-axis
