If \( f(x)=\frac{\sqrt{x+2}}{3-3 x^{2}} \), for which values of \( x \) is \( 1.22 \quad f(x) \) non real \( 1.23 \quad f(x) \) undefined \( 12.4 \quad f(x)>0 \)

Sketch on the same set of axes the graphs of \( f(x)=-2 x^{2}-4 x+6 \) and \( g(x)=-2 \cdot 2^{x-1}+1 \) Clearly indicate all intercepts with the axes, turning point(s) and asymptote(s).

Identify the trace of the surface \( 3 x+2 x^{2}-z^{2}-2 y=5 \) on \( y z \)-plase \( \begin{array}{llll}\text { A. Ellipse } & \text { (B) Circle } & \text { C. Hyperbola } & \text { D. Par }\end{array} \)

5. \( \forall \alpha \in \mathbb{R} \) için, \( A=-2 \sin \alpha+1 \) olduğuna göre, A nın değer aralığı nedir?

3-Determine the domain of \( f(x, y)=\sqrt{x^{2}-9}-\ln (y-1) \) \[ \begin{array}{ll}\text { (a) }|x| \geq 3 \text { and } y>1 & \text { (b) }|x| \leq 3 \\ \text { (c) }|x| \geq 3 \text { and } y=1 & \end{array} \]

La función es continua en el punto dado: \( f(x)=3 x+2 \) en el intervalo \( [0,3) \) Verdadero Falso
