For the graph defined $byan$ equation $of$ the form $y=a{b}^x,$ given $a<mn>0</mn>$ :

$a\{xinR\}.$

$b\{y>0,$yinR$\}.$

$cy-$intercept $is1.$

$dy=secx?$

$a\{-1x1,$xinR$\}$

$borx1,$xinR

$c\{xk,$kinI,xinR$\}$

$d\{x\frac{2k+1}{2},$kinI,xinR$\}$

$ef(x)=2^x$ and $g(x)=\sqrt[\phantom{2}]{x-2},$ then the domain $offgis$:

$a\{xin\}$

$b\{x2,$xin$\}$

$c\{x2,$xin$\}$

$d\{x=0\}$

$ef(x)=4x^3-5$ and $g(x)=\frac{1}{x},$ then $g$@$f(2)$

$a\frac{1}{27}$

$b\frac{-2}{5}$

$c\frac{1}{3}$
