One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3
and slope m =
So the equation of line will be
And the inequality should be
Or
And the other line passes through (-2,3) and (0,2)
So the y intercept is b=2
and the slope is
So the equation of line will be
Or
So answer is
By solving a quadratic equation, it can be verified that
The owl population will disappear after 329.12 years
What is a quadratic equation?
At first it is important to know about equation
Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A two degree equation is known as quadratic equation.
Here, a quadratic equation needs to be solved
The decreasing population, p, of owls in a national park is being monitored by ecologists and is modeled by the equation p=
For population to disappear, p =0
But t = -9.115 is not possible as time cannot be negative
So, the owl population will disappear after 329.12 years
