Suppose that the functions \( g \) and \( h \) are defined as follows. \[ \begin{aligned} g(x)=5-3 x^{2} \\ h(x)=9-2 x\end{aligned} \] (a) Find \( \left(\frac{g}{h}\right) \) (2). (b) Find all values that are NOT in the domain of \( \frac{g}{h} \). If there is more than one value, separate them with commas. (a) \( \left(\frac{g}{h}\right) \) (2) = (b) Value(s) that are NOT in the domain of \( \frac{g}{h}: \square \)

\( \frac{a+b}{a^{2}+b^{2}+2 a b}-a b \quad \) per \( a=4 ; b=-3 \)

Write the coefficient of: (a) \( y \) in \( -3 x^{2} y \)

1) \( (3 x)\left(2 x^{2}\right) \) 4) \( \left(x^{3}\right)\left(x^{2}+x\right)\left(3 x^{3}\right) \) 7) \( \left(x^{4}+3 x^{3}+2 x^{2}+11 x\right)\left(x^{3}\right) \)

If \( (2 a-5)(3 a-2)=6 a^{2}+k a+10 \), then \( k= \) \( \begin{array}{llll}\text { (a) } 15 & \text { (b) } 19 & \text { (c) }-19 & \text { (d) } 6\end{array} \)

\[ y=-3 x^{2}+12 x-15 \] Write your answer as an inequality using \( x \) or \( y \) as appropriate. Or, you may instead click on "Empty set" or "All reals" as the answer.
