The rate of change of the linear equation is
Explanation:
The given two coordinates are and
To determine the rate of change, let us use the formula,
Substituting the coordinates in the equation, we get,
Simplifying, we have,
Dividing, we get,
Thus, the rate of change of the linear equation is
Option C
The zeros of the polynomial function f(x) = x^3 - 5x^2 - 6x is x = 0 and x = -1 and x = 6
<h3><u>Solution:</u></h3>Given that polynomial function is f(x) = x^3 - 5x^2 - 6x
We have to find the zeros of polynomial
To find zeros, equate the given polynomial function to 0. i.e f(x) = 0
Taking "x" as common term,
Equating each term to zero, we get
Thus one of the zeros of function is x = 0
Now let us solve
We can rewrite -5x as -6x + x
Taking "x" as common from first two terms and -6 as common from next two terms
Taking (x + 1) as common term,
(x + 1)(x - 6) = 0
x + 1 = 0 and x - 6 = 0
x = -1 and x = 6
Thus the zeros of given function is x = 0 and x = -1 and x = 6
