Composite FunctionsDate: 4/5/96 at 2:0:53 From: Brac Subject: Math I need a detailed solution for these math equations: 1) fog(x) = 7x + 3 gof(x) = 7x - 3 f(0) = 1 g(0) = ....... 2) 5x^2 + log(x) = 0 log(10) = 1 x = ........

Use this information to get an equation for g and then just evaluate it at g(0). -Doctor John, The Math Forum |
