"If t is a number greater than one then t^2 is how many times greater than t" The answer was 2. My incorrect solution: I substituted 3 for t. Thus t^2=9. 9 is 3x greater than 3. Thus my answer was "t".Why was my answer wrong??? 2. for the problems that gives a table with a list x and y values and asks you to find the function equation, what is the fastest way to solve the problem? I usually just guess and check each of the choices until I find the equation that works but doing so takes a long time. Thanks for all your help! Reply
