Write either the function or the name of each organelle. Draw a sketch to help you remember it.

Organelle	Function	Sketch
ribosomes

Sketch the appropriate traces, and then sketch and identify the surface. $\frac{x^{2}}{4}+\frac{y^{2}}{4}+\frac{z^{2}}{9}=1$

Sketch a triangle described by each pair of words below or state that it is not possible. If it is not possible to sketch a triangle, explain why not. isosceles, right

In the following exercise, classify and sketch the quadric surface. Use a graphing utility to confirm your sketch.

$$x^2-y^2+z=0$$

Sketch the graph of the function. f(x)=-[[x]]

Sketch a graph that is not that of a function.

Find the exact x-intercepts and vertex of $y=(x+2)^{2}-3$. Make a sketch, then check your sketch with your graphing calculator.

Sketch a triangle described by each pair of words below or state that it is not possible. If it is not possible to sketch a triangle, explain why not. isosceles, obtuse

Sketch the graph of $y=-x+\cos x$.

Sketch the graph of $f(x)=\frac{1}{x-4}$. Let $g(x)=f(x+2)-1$. Write g(x) explicitly and sketch its graph.

Sketch the graph of y = sin |x|.

Sketch and label $\overrightarrow{A B}$.

(a) Find the foci and asymptotes of the hyperbola $x^2 - y^2 = 1$ and sketch its graph.

(b) Sketch the graph of $y^2 - x^2 = 1$.
