Thus, if you order a large pizza with x toppings, the price of your pizza is given by the function f(x)=7+2x. Find f(-1) (inverse, f of negative one). What does the function f(-1)represent? \n" ); document.write( "
Algebra.Com's Answer #421339 by fcabanski(1391)![]() ![]() ![]() You can put this solution on YOUR website! f(x)=7+2x is the same as saying y=7+2x. To find the inverse 1. solve for x (get x by itself). then 2. Replace x with y and y with x.
Hope the solution helped. Sometimes you need more than a solution. Contact fcabanski@hotmail.com for online, private tutoring, or personalized problem solving (quick for groups of problems.) \n" ); document.write( " |
