91 Inverse functions Informally, two functions f and g are inverses if each reverses, or undoes, the other More precisely Definition 911 Two functions f and g are inverses if for all x in the domain of g , f(g(x)) = x, and for all x in the domain of f, g(f(x)) = x Example 912 f = x3 and g = x1 / 3 are inverses, since (x3)1 / 3 = xPlease Subscribe here, thank you!!!For every function f, subset X of the domain and subset Y of the codomain, X ⊂ f −1 (f(X)) and f(f −1 (Y)) ⊂ Y If f is injective, then X = f −1 (f(X)), and if f is surjective, then f(f −1 (Y)) = Y For every function h X → Y, one can define a surjection H X → h(X) x → h(x) and an injection I h(X

Solution for F(x)= x^24 f(2)f(h)Eq1) or equivalently if the following equation holds for all such x f (x) − f (− x) = 0 {\displaystyle f(x)f(x)=0} Geometrically, the graph of an even function is symmetric with respect to the y axis, meaning that its graph remains unchanged after reflection about the y axis Examples of even functions are The absolute value x ↦ x , {\displaystyle x\mapsto x,} x ↦ x 2Δ = b 24ac Δ = 4 24·1·(1) Δ = The delta value is higher than zero, so the equation has two solutions We use following formulas to calculate our solutions
