Find the zeros of the function f(x)=-1.3x^2-15.7x-44.2 . Round values to the nearest hundredth (if necessary).

Step-by-step explanation:

Given

The solution of the standard quadratic equation has solution

Applying the above principle

The zeroes of the equation are -7.60, -4.47.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
