Let \(f(x)=\sqrt[3]{x}\). Write a rule for \(g\) that represents the indicated transformation of the graph of \(f\). \(g(x)=f(x+2)\)
Solve the equation. Check for extraneous solutions. \(\log _5(x+4)+\log _5(x+1)=2\)
In Exercises 3–12, simplify the expression. $$ \left(5 e^{7 x}\right)^4 $$
PROBLEM SOLVING A study in Florida found that the number \(s\) of fish species in a pool or lake can be modeled by the function $$ s=30.6-20.5 \log A+3.8(\log A)^2 $$ where \(A\) is the area (in square meters) of the pool or lake. a. Use a graphing calculator to graph the function on the domain \(200 \leq A \leq 35,000\). b. Use your graph to estimate the number of species in a lake with an area of 30,000 square meters. c. Use your graph to estimate the area of a lake that contains six species of fish. d. Describe what happens to the number of fish species as the area of a pool or lake increases. Explain why your answer makes sense.
In Exercises 31-34, use a table of values or a graphing calculator to graph the function. Then identify the domain and range. $$ y=e^{x+1} $$
