A relation is what it sounds like. A relation between numbers and/or objects.

A function is just a special type of relationship. In order for a relation to be a function, it must have only one output for one input.

On a graph, the x-axis is the input and the y-axis is the output. If you draw a vertical line through a point on the x-axis and there is only one point on that vertical line, then it is a function.

The only graph that meets these criteria is the first graph.

\dfrac{f(x+h)+f(x)}{h}

Replace f(x) and f(x+h) by using the equation given for the problem.

=\dfrac{(2(x+h)^2-(x+h)-1)-(2x^2-x-1)}{h}

Open all parenthesis

= \dfrac{2x^2+4xh+2h^2-x-h-1-2x^2+x+1}{h}

Factor the h

= \dfrac{h(4x+2h-1)+2x^2-2x^2+1-1+x-x}{h}

Other terms not in the parenthesis cancel each other out

\dfrac{h(4x+2h-1)}{h}

Now, simplify

=4x+2h-1

Ad libitum [116K]

Answer: B.  |x-100| = 25

Explanation:

Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.

The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
