WebGiven f (x) = 3x + 2 and g(x) = 4 − 5x, find (f + g) (x), (f − g) (x), (f × g) (x), and (f / g) (x). To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to. ( f + g ) ( x) = f ( x) + g ( x) = [3 x + 2] + [4 − 5 x] = 3 x + 2 + 4 − 5 x = 3 x − 5 x + 2 + 4 WebOct 18, 2015 · Solving for (f ∘ g ) (x) watch fully. College Algebra getting to you?

WebIt gives a clue that there could possibly be f^2 meaning f(f(x)). This would mean that (f \times g)(x) = f(g(x)). NOTE: In latex \times is a vector cross product. I use to distinguish it from the ordinary multiplication. The same as cross product, this type of multiplication is … Learn for free about math, art, computer programming, economics, physics, … And we are subtracting f of x from g of x. So let's subtract, this is f of x, from g of x. … Learn for free about math, art, computer programming, economics, physics, … WebGraph f (x)=g (x) ? f (x) = g(x) f ( x) = g ( x) ? Rewrite the function as an equation. y = g(x) y = g ( x) Multiply g g by x x. y = gx y = g x Use the slope-intercept form to find the slope and y … WebAssuming f ∘ f = g, let a = f ( 0), then f ( a) = 1 and f ( 1) = g ( a) = a since a ∉ { 0, 1 } . Then g ( 1) = f ( f ( 1)) = f ( a) = 1, a contradiction. Q2: No. Let g ( x) = − x or, in fact, any decreasing function R → R. Then f must be injective and hence monotone. Whether f is increasing or decreasing, f ∘ f is increasing. Share Cite cryptography lua
