Answer 1

a) $f(x)=5^x$

Is $f(x)=5^x$ defined at any values of $x$ ? Yes.

What is the minimum value of $f(x)$ ? Cannot be defined.

Can you determine the maximum value of $f(x)$ No.

b) $f(x)=(\dfrac{1}{5})^{3x}$

Is $f(x)=(\dfrac{1}{5})^{3x}$ defined at any values of $x$ ? Yes.

What is the minimum value of $f(x)$ ? Cannot be defined.

Can you determine the maximum value of $f(x)$ No.

c) $f(x)=\dfrac{1}{3}(2)^{x}+3$

Which is $P(x)$? $x$ Is $P(x)$ linear? Yes.

Is $a>0$ or $a<0$ ? $a>0$

What is value of $h$ ? $3$

$\def\arraystretch{1.5} \begin{array}{c:c:c} & Domain & Range \\ \hline Set\ notation & \R & \{y\in \R|y>3\} \\ \hdashline Interval\ notation & (-\infin,\infin) & (3,\infin) \end{array}$

d) $g(x)=-(4)^{2x-3}+1$

Which is $P(x)$? $2x-3$ Is $P(x)$ linear? Yes.

Is $a>0$ or $a<0$ ? $a<0$

What is value of $h$ ? $1$

$\def\arraystretch{1.5} \begin{array}{c:c:c} & Domain & Range \\ \hline Set\ notation & \R & \{y\in \R|y<1\} \\ \hdashline Interval\ notation & (-\infin,\infin) & (-\infin, 1) \end{array}$

e) $h(x)=2(3)^{3x-1}+2$

Which is $P(x)$? $3x-1$ Is $P(x)$ linear? Yes.

Is $a>0$ or $a<0$ ? $a>0$

What is value of $h$ ? $2$

$\def\arraystretch{1.5} \begin{array}{c:c:c} & Domain & Range \\ \hline Set\ notation & \R & \{y\in \R|y>2\} \\ \hdashline Interval\ notation & (-\infin,\infin) & (2,\infin) \end{array}$
