Step 1
The number of such functions is determined by the number of choices for each element in \( X \). ### a. Find all functions from \( X = \{a, b\} \) to \( Y = \{u, v\} \). For each element in \( X \), we have 2 choices in \( Y \) (either \( u \) or \( v \)). - Show more…

(a) find two explicit functions by solving the equation for $y$ in terms of $x$, (b) sketch the graph of the equation and label the parts given by the corresponding explicit functions, (c) differentiate the explicit functions, and (d) find $d y / d x$ implicitly and show that the result is equivalent to that of part (c). $$ 4 y^{2}-x^{2}=4 $$
Differentiation
Implicit Differentiation
Find $f_{x x}(x, y), f_{x y}(x, y), f_{y x}(x, y),$ and $f_{v v}(x, y)$ for each function $f$. $$ f(x, y)=\frac{x^{2}}{y}-\frac{y^{2}}{x} $$

Partial Derivatives
For each pair of functions, find (a) $(f \circ g)(1)$ (b) $(g \circ f)(1) ;(\mathbf{c})(f \circ g)(x) ;$ and $(\mathbf{d})(g \circ f)(x)$. $$f(x)=3 x^{2}+4 ; g(x)=4 x-1$$
