- Use log21=0,log22=1, and log24=2 to estimate log23.arrow_forwardThe number N of beavers in a given area after x years can be approximated by N=5.5100.23x,0x10. Use the model to approximate how many years it will take for the beaver population to reach 78.arrow_forwardRecall that an exponential function is any equationwritten in the form f(x)=abx such that a and b arepositive numbers and b1. Any positive numberb; can be written as b=en for some value of n. Usethis fact to rewrite the formula for an exponentialfunction that uses the number e as a base.arrow_forward
