F(x) = x^2 + 2x -1
Domain all real number
Range: all real numbers equal or greater than -2.
To find the range you need to find the vertex of the parabole, which is (-1,-2) and use the fact that, given that the coefficient of x^2 is positive, the funcion open upwards (which means that the vertex is a global minimum).
To find the vertex you use the quadratic formula to find the roots and then the x-coordinate of the vertex is in the middle of the two roots.

Hello,
To find out if the ordered pair is a solution to the inequality substitute x and y of the ordered pair into the problem.
<span>y≥−6x−3
Solution:
</span><span>-2≥−6(1)−3
-2</span>≥-6-3
-2≥-9
-2 is greater than -9. Thus, <span>(1,-2) is a solution of y≥−6x−3.

Answer:
267.9 feet^3
Step-by-step explanation:
V = 4/3πr^3
4/3 * 3.14 * 4^3 = 267.946666
