Answer:

Vertex: The common end point at which the two rays meet to form an angle is called the vertex. Here, the point O is the vertex of ∠AOB. We can find angles in various things around us, such as in a pair of scissors, a hockey stick, a chair.

Please help me on 17-18!<br> I have no clue on what to do on the problems at hand.
nika2105 [10]

If you would have to graph x=7, you probably know that this is a vertical line at, well, x=7.

| x | = 7 is nothing more than two vertical lines, namely x=7 or x=-7, as you already wrote down.

| x | = -8 has no (real) solutions, so there is nothing to graph.

Find the values of m and b that make the following function differentiable.
dimaraw [331]
Now, bearing in mind that, for a graph, to be "differentiable", means a "smooth transition", not an abrupt edge or a "cusp", the first subfunction of the piece-wise is just a quadratic, the second subfunction is a linear, well, so the linear needs to hit the quadratic "smoothly", not make an abrupt edge, for that, the linear must continue the quadratic from 2 onwards, since 2 is the range edge.

now, what is the piece-wise when x = 2? well, f(2) = x² or (2)² or 4

that means, the linear needs to hit it at that point, to make it so, let's make it the slope of the linear, the same as the quadratic's.

what's the quadratic's slope? well, simple enough

\bf \left. \cfrac{dy}{dx}=2x \right|_{x=2}\implies 4\impliedby \textit{this means }&#10;\begin{array}{llll}&#10;mx+b\\&#10;\uparrow \\&#10;4&#10;\end{array}

so we have y = 4x + b

now, recall, for the quadratic, when x =2, y = 4, so for the linear, when x = 2, y = 4 as well, this means

\bf 4 = 4(2) + b\implies 4=8+b\implies 4-8=b\implies \boxed{-4=b}&#10;\\\\\\&#10;mx+b\implies 4x-4\\\\&#10;-------------------------------\\\\&#10;f(x)=&#10;\begin{cases}&#10;x^2&x\le 2\\&#10;4x-4&x\ \textgreater \ 2&#10;\end{cases}

check the picture below.
