How do i find f -1
WebOct 8, 2015 · to find: f '(x) = 1 √1 + 2x Explanation: Let f (x) = √1 + 2x Then the derivative at x = a is defined as the following limit: f '(a) = lim h→0 f (a + h) −f (a) h = lim h→0 √1 + 2(a +h) − √1 + 2a h = lim h→0 √1 + 2(a +h) − √1 + 2a h ⋅ √1 + 2(a + h) +√1 +2a √1 + 2(a + h) +√1 +2a WebThe function f(x) = x2/ (x2+1), x≥0 The restriction is important to make it 1-1. Start with the function: f(x) = x2/ (x2+1), x≥0 Replace f(x) by y: y = x2/ (x2+1), x≥0 Switch the x's and y's: x = y2/ (y2+1), y ≥0 Solve for y: Multiply by denominator: x(y2+1) = y2 Distribute: xy2+ x = y2
