If f (x) is an exponential function where f(-2.5) = 9 and f(7) = 91, then find the value of f(12), to the nearest hundredth.

Can someone explain the elimination method to me for this problem?

The long jump record, in feet, at a particular school can be modeled by f(x) = 19.6 + 2.5ln(x + 1) where x is the number of years since records began to be kept at the school. what is the record for the long jump 11 years after record started being kept? round your answer to the nearest tenth.

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!
