Find a simplified expression for f g x
Did you know?
WebGiven f (x) = x2 + 2x − 1, evaluate f (§). Well, evaluating a function means plugging whatever they gave me in for the argument in the formula. This means that I have to plug this character " § " in for every instance of x. Here goes: f (§) = (§) 2 + 2 (§) − 1 = § 2 + 2§ − 1 WebAssuming that 𝑔 is a linear polynomial function in 𝑥. Then we have: 𝑔(𝑥 + 6) = 5𝑥 + 8 The variable we use doesn't matter, so to avoid confusion, we will write this functional equation in 𝑘 instead of 𝑥:

WebTo do this, we must compose the two functions and find f (g (x)) f (g(x)). Example What is f (g (x)) f (g(x))? For reference, remember that f (x)=3x-1 f (x) = 3x −1 and g (x)=x^3+2 g(x) = x3 +2. Solution If we look at the expression f (\maroonD {g (x)}) f (g(x)), we can see that \maroonD {g (x)} g(x) is the input of function f f. WebSo for finding f (g (x)), we have to first find g (x) and then take g (x) as input of f (x) and simplify. Here is an example to understand this. Let us assume that f (x) = 2x + 3 and g (x) = x 2. We will find f (g (3)). For this: Step 1: …
WebFor example, if f(x) = x + 1, and g(x) = x^2, finding f(g(x)) wouldn't most likely be regarded as hard, since you can simply substitute the x^2 in to get f(g(x)) = x^2 + 1 However, if you were given a harder example, such as f(x) = (x + tanxsecx - x!/sqrt(x)) and g(x) = cscx * …

Showing just one proves that f and g are inverses. You know a function is invertible if it doesn't hit the same value twice (e.g. if the functions is strictly increasing or decreasing).
