Unit 4 Exponential and Logarithmic Functions Review

Find the equation of the model of best fit for the set of data:

• f(x) = 2.7x + 1.2

• f(x) = 0.75x² + 0.45x + 1.95

• f(x) = x² + 2

• f(x) = 1.9(1.74)^x

Express in logarithmic form: 1024 = 4⁵

• log₅(4) = 1024

• log₅(1024) = 4

• log₄(5) = 1024

• log₄(1024) = 5
