Given f x x − 7 and g x x2 find f g 4
WebYour function g(x) is defined as a combined function of g(f(x)), so you don't have a plain g(x) that you can just evaluate using 5. The 5 needs to be the output from f(x). So, start by finding: 5=1+2x That get's you back to the original input value that you can then use as the input to g(f(x)). Subtract 1: 4=2x Divided by 2: x=2 WebExplain why f has a removable discontinuity at x = 4. (Select all that apply.) a. f(4) and lim x→4 f(x) exist, but are not equal. b. lim x→4 f(x) does not exists. c. f(4) is undefined. d. lim x→4 f(x) exists. e. none of the above. b. Explain why the function is discontinuous at the given number a. (Select all that apply.)

WebFree functions composition calculator - solve functions compositions step-by-step WebThe resulting function is known as a composite function. We represent this combination by the following notation: (f ∘ g)(x) = f(g(x)) We read the left-hand side as “f composed with g at x ,” and the right-hand side as “f of g of x. ” The two sides of the equation have the same mathematical meaning and are equal.

For functions f and g, the composition is written f ∘ g and is defined by (f ∘ g)(x) = f(g(x)). We read f(g(x)) as “f of g of x.”. To do a composition, the output of the first function, g(x), becomes the input of the second function, f, and so we must be sure ...

WebNov 1, 2024 · The answer is f(g(4)) = 9. Since f(x) = x - 7 and g(x) = x², to find f(g(4)), we first need to find f(g(x)). We find this by substituting g(x) into f(x) by replacing x with g(x) So, f(x) = x - 7. f(g(x)) = g(x) - 7. Since g(x) = x², Substituting the value of g(x) into the equation, we have. f(g(x)) = g(x) - 7. Replacing g(x) with x², we have ... pubs with rooms near wells somersetWebThis problem has been solved!

First we need to plug in -1 for x in g(x). Therefore, g(-1) = (-1)² = 1. Moving on, we can then plug in 1 as the value of x into f(x). And consequently, we have f(1) = 1 - 7 = -6. Therefore, the value of f(g(-1)) given: f(x) = x-7 and g(x) = x² is f(g(-1)) = -6.
