Exponential and Logarithmic Regression

Bacteria was put in a petri dish with antibacterial soap. Determine the logarithmic regression of the bacteria. Use either a calculator or spreadsheet program.

f(x)=253.8−75.94ln(x)

f(x)=253.8+75.94ln(x)

f(x)=−253.8+75.94ln(x)

f(x)=253.8−98.2ln(x)

1 POINT

Using the data below, find the exponential regression relating the value of a car over 10 years using either a calculator or spreadsheet program.

f(x)=88.5⋅0.797x

f(x)=88.5⋅0.797x

f(x)=−88.5⋅0.797x

f(x)=88.5⋅(−0.797)x

QUESTION 3

·Determine the exponential regression of the data below using either a calculator or spreadsheet program.

(60,5),(61,14),(62,23),(63,49),(64,67),(65,78)

Select the correct answer below:

f(x)=−3.6×10−14⋅0.17x

f(x)=0.036⋅1.7x

f(x)=3.6×10−14⋅1.7x

f(x)=−3.6×10−14⋅1.7x
