Determine the number of zeros of the polynomial function. f(x) = x3 + 4x2 + 1

  1 real zero; 2 complex zeros

Step-by-step explanation:

A cubic will have 3 zeros. The number of positive and negative real zeros can be determined using Descartes' rule of signs.

There are no sign changes in the coefficients of the function as written, so there are no positive real roots. (+++)

If odd-degree terms have their sign changed, then there is one sign change. (-++) That indicates there is one negative real root.

The remaining two roots will be complex.

A graphing calculator can confirm this.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

yes   because as the functions are graphed they eventually will intersect unless otherwise
