Review Lesson 7-1: Without graphing, determine whether the function represents exponential growth or decay.
f\left(x\right)=3\left(5\right)^x
y=5\left(\frac{8}{3}\right)^x
y=2\left(\frac{3}{4}\right)^x
y=23\left(3.03\right)^x
Exponential growth
Exponential decay
Review Lesson 7-1: Without graphing, find the y-intercept of each exponential function.
y=2\left(\frac{3}{4}\right)^x
y=23\left(3.03\right)^x
y=5\left(\frac{8}{3}\right)^x
f\left(x\right)=3\left(5\right)^x
y-intercept: 2
y-intercept: 23
y-intercept: 3
y-intercept: 5
Review Lesson 6-7: Find the inverse of each function on the right and state whether the inverse is a function or is not a function.
f^{-1}\left(x\right)=\sqrt[4]{x}
f^{-1}\left(x\right)=\frac{x+1}{4}
f -1 is a function
f -1 is NOT a function
f\left(x\right)=4x-1
f\left(x\right)=x^4
Vocabulary Review: In each graph, the dashed figure is the image of the solid figure after a transformation. Categorize each transformation as a translation, reflection, or dilation.
Translation
Reflection
Dilation
Use Your Vocabulary: Identify the functions that represent exponential growth. Select all that apply.
y=2.5\left(0.75\right)^x
y=0.8\left(2.7\right)^x
y=6\left(x-9.3\right)^2
y=6\left(9.3\right)^x
y=-5\left(1.02\right)^x
