Solution Summary: The author explains how to sketch the graph of the function y=x4 and its transformation.
a) Graph the function on the coordinate plane.
n(x) = -(x + 4)² + 2
y
b) Describe the transformation of your graph from the parent function f(x) = x²
In 2010, an investor put money into a fund. The graph below shows the value v = v(d) of the investment, in dollars, as a function of the date d.

Explain what this means about the growth in value of the account.
This means that the investment is increasing
(c) In what year will the value of the investment reach $105,000?
2050
(d) What is the average yearly increase from 2050 to 2060?
$
per year
at an increasing ✓
Explain your reasoning.
(e) Which is larger, the average yearly increase from 2050 to 2060 or the average yearly increase from 2010 to 2020?
2010 to 2020

C. The average yearly increase from 2050 to 2060 is $
Evaluate each expression using the graphs of y = f(x) and y = g(x) shown below.
(a) (g o f)( - 1)
(b) (g o f)(0)
(c) (fo g)(- 1)
(d) (fo g)(4)
(a) (g o f)( – 1) = D
(Simplify your answer.)
y= g(x)
(b) (g o f)(0) =D
(Simplify your answer.)
(c) (fo g)(- 1) =
(Simplify your answer.)
