Is f of x a function
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 WebStep 1: Identify the function f(x) f ( x) for which we are taking its first derivative at the point x = a, f′(a) x = a, f ′ ( a). Step 2: Choose either the difference quotient or...
