A one-to-one function is given. Write an equation for the inverse function. $g(x)=b(x+a)^{3}+c$

Use the graph of f(x) to describe the transformation that results in the graph of g(x). than sketch the graphs of f(x) and g(x). $f(x)=\ln x ; g(x)=\ln (-x)$

The nth term of a sequence is given. Write the first four terms of the sequence. $b_{n}=\sqrt{n-1}$

The function g is defined by $g(x) = 2f(x+3) - 4$. Explain how the behavior of function g compares to the behavior of function f.

The motion of an object traveling along a straight path is given by $s(t)=\frac{1}{2} a t^{2}+v_{0} t+s_{0},$ where s(t) is the position relative to the origin at time t. For this exercise, three observed data points are given. Find the yalues of a, $\(v_{0},\) and \(s_{0}\).$ $s(1)=-7, s(2)=12, s(3)=37$

A lab received a sample of an isotope of cobalt in 1999. The amount of cobalt in grams remaining per year is shown in the table below.

Find a logarithmic function to model the data. Let x=1 represent 2000.

A spider is slowly climbing up a wall. Brianna is standing 6 feet away from the wall watching the spider. Let d be the distance Brianna is from the spider and $\theta$ be the angle of elevation of the spider from Brianna. Approximately how far away is the spider from Brianna when the angle of elevation is $32^{\circ} ?$
