Exponential Functions - Equations: Problem 8 (1 point) Challenge Problem: 3- 7er Solve for c: 5- 4el = 17 . If you give a decimal approximation, your answer must be accurate to at least 3 decimal places.(1,9) (0,6) Assuming that f(a) is of the form A . BY, write an expression for f (I): f(I) =(0,5) (1,3) Assuming that f(a) is of the form A . BI, write an expression for f (I):\f(Br-2} (2,-4} Assuming that x} is of the form A - 33, write an expression for x): HI) =E] Practice (1,7) (0,1) Assuming that f(x) is of the form A . BY, write an expression for f (I): f(x) =Properties that can be useful in solving exponential equations are: . In(b") = aln(b) . In(ab) = In(a) + In(b) . In (7 = In(a) - In(b) . When a = b then In(a) = In(b). Practice Solve for : 487 8 _ 971-7 . If you give a decimal approximation, your answer must be accurate to at least 3 decimal places. C =
