119 If the domain of f is an interval or all of R and if F is an antiderivative of f, then all other antiderivatives are obtained by adding any constant function to F. GeoGebra Integral [, ] TI Nspire integral (Expr, Var) (Note: The integration constant is not displayed.) 408 Check whether the function F with F (x) = 5x 2 - 3x + 2 or the function G with G (x) = 5x 2 + 3x - 2 is an antiderivative of the function f with f (x) = 10x + 3. The derivative of F is F 'with F' (x) = 10x - 3 ≠ f (x), so F is not an antiderivative of f. The derivative of G is G 'with G' (x) = 10x + 3 = f (x), so G is an antiderivative of f. 409 Check whether the function F with F (x) = 5x 3 + 4x 2 - 3x + 7 or the function G with G (x) = 5x 3 - 4x 2 - 7x is an antiderivative of the function f with f (x) = 15x 2 + 8x - 3. 410 Show that both F with F (x) = 3x 2 + 4x + 7 and G with G (x) = 3x 2 + 4x - 9 are antiderivatives of the function f with f (x) = 6x + 4. 411 Tick which of the functions are parent functions of f 'with f' (x) = 12x 3 - 9x 2 + 8x - 1.
