help on math problems
I need help on solving these math problems in one of the practice tests
1. "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!
