(a) f ( x ) = 4-log 3 x (b) g ( x ) = 2 x + 1 (c) h ( x ) = 3 e-x + 2 Equations. You should be able to not only simplify expressions, but also solve equations involving exponentials and logs. 6. Solve each of the following equations for x . (Note: At least one of these equations has no solution.) (a) e 3 x = (5 /e ) x +1 (b) 3 x · 5 3 x +1 = 0 (c) log x-log( x + 1) = 2 (d) ln √ x + ln x 2 = 1-2 ln x (e) e x ( e x-5) = 6 (f) 2 e 2 x + 6 = 7 e x...
