For the given functions of each composite functions f and g, find f of g, g of f, f of f, g of g if g(x)=x1/x2 and h(x) = 4 – x, what is the value of g(h(3)) In this problem we will find out the value of the function composition There are two ways to do it Option 1 Step1 compose (g o h)(x) = g(h(x)) Here h(x) as input into g(x) In other words, first we apply h(x), then apply g(x) to that result And we get, Step2 calculate the value of g(h(3)) After getting g(h(x))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 2
The domain of the function is ( − ∞,2) ∪ (2, ∞) We can simplify in this way y = (x −2)(x 2) x − 2 = x 2 Since the range of y = x 2 is R, seems that the range is R, but we have that x ≠ 2 so the range is y ≠ 4, because the graph is a line without the point P (2,4) graph { (x^24)/ (x2) 10, 10, 5, 5} Answer linkRelations and Functions II 504 150 If g −2,2 → R, where f (x) = x3 tanx P x2 1 is an odd function, then the value of parametric P, whereSolve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more
