The subtraction theorem states that for all real numbers, a and b, a-b=a+(-b).
(To subtract, we can add the inverse.)
Thus, we can have the these two equivalent expressions.

3 - 2 = 3 + (-2) = 1\\ \\ 5 - (-2) = 5 + 2 = 7

What is the range of the function f(x) = 3x2 + 6x – 8?
oee [108]

f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.

, written in vertex form is

, where (h, k) = (-1, -11)

Therefore, range ={y|y ≥ -11}

The weight can be:

1) smaller than or equal to 20 oz + 0.4 oz:    then  

2) larger than or equal to 20 oz - 0.4 oz:    then  

and which combined, can be written as a double inequality;

This double condition can also be written using the absolute value symbol as:
