f of g of x is also known as a composite function and it is mathematically denoted as f(g(x)) or (f ∘ g)(x) and it means that x = g(x) should be substituted in f(x). It is also read as "f circle g of x". It is an operation that combines two functions to form another new function. In f of g of x, the output of one function becomes the input of the other function.
Graph f(x)=|x| Step 1. Find the absolute value vertex. In this case, the vertex for is . Tap for more steps... Step 1.1. To find the coordinate of the vertex, set the inside of the absolute value equal to . In this case, . Step 1.2. Replace the variable with in the expression. Step 1.3.
3. (20 Points) Let {ωv 1,ωv 2,ωv 3} be an orthonormal basisofR3 and let A be the matrix formed by taking ω v 1 as first column, ω v 2 as second column, and ωv 3 as third column. Also let B = 10 0 01 0 00⇒1 (a) Show that ABA↑1 represents reflection with respect to the plane containing ω v 1 and ωv 2,and that ⇒ABA↑1 represents rotation by ε about the axis determined by ωv
For g∘ f(x) g∘f(x) = g(f(x)) ⇒ g∘f(x) = g(e x) ⇒ g∘f(x) = (e x) 2 + 1 ⇒ g∘f(x) = e 2x + 1. Example 2: For the given functions f(x) = 2x and g(x) = x 2 + 1. Find out the values of f(g(x)) and g(f(x)) at x = 2. Solution: The domain of both the functions are real numbers, so there is no need to modify the domain for the first ...

What is f(x)? It is a different way of writing "y" in equations, but it's much more useful!
of the terms f(x±h) are f(x±h) = f(x)±hf0(x)+ h2 2 f00(x)± h3 6 f000(x)+ h4 24 f(4)(ξ ±), (5.13) where (assuming that h > 0) x−h 6 ξ − 6 x 6 ξ + 6 x+h. Using the expansions in (5.13) we can rewrite (5.12) as f00(x) ≈ Af(x+h)+Bf(x)+Cf(x−h) (5.14) = (A+B +C)f(x)+h(A−C)f0(x)+ h2 2 (A+C)f00(x) + h3 6 (A−C)f(3)(x)+ h4 24 [Af(4 ...
