Justify Why is f(x) = 4(1)x not an exponential function? Multiple Choice Which could be the function graphed?
_1 x A y = -(2)
C y = -(2)x
Population The exponential function y = 20.85(1.0212)x can model the
approximate population of Texas from 2000 to 2006, where x is the number
of years after 2000 and y represents millions of people. Assuming the model
does not change, what is the difference in expected populations for 2010 and 2020?
Verify Show that the set {(3, -4), (2, -1), (5, -64), (4, -16)} is an exponential function when b = 4.
Name the corresponding sides and angles if ΔRST ∼ ΔNVQ.
Multi-Step Graph the parent function f (x) = ⎢x . Translate the function down
by 2. Then reflect the function across the x-axis. What is the new function? Is the graph an absolute-value function? Explain.

Error Analysis Two students found the solution to a radical equation. Which student is correct? Explain the error.
Solve √x - 2 = 8. Check your answer.

Student A
√ x + 3 = 6 x + 9 = 36 x = 27
Student B
√ x + 3 = 6 x + 3 = 36 x = 33
