[Explicit rule: f(n)=f(1)+f(n)(r)] [Recursive rule: 2 steps: find what f(0)=x f(n-1)+r] [arithmetic sequence: you have the same ratio everytime and you are adding] [geometric sequence: multiply by the same amount to get next #. use Formula ar^n-1=the last given # in sequence] |

compound interest formula A=p(1+r/n)^(nt)] [continuous interest formula A= Pe^(rt)] [To find inverse replace x and y and solve for y] [fraction outside parentheses= horizontally stretched, inside = vertically compressed] [to graph inverse reflect across diagonal line/] [when asked about a # less than 1 it is decay ex. 0.2^x is decay] [more than 1 is growth ex. 5^x is growth when it is a -x it is decay] [for exponential equation ex. 3^x-3 -5=-2 add 5 then use logs.] |
