WebFeb 3, 2016 · This means that you must plug in h into g. Explanation: g(h(x)) = g(3x + 9) = #5(3x + 9)^2 - 4(3x + 9)# = #5(9x^2 + 54x + 81 ) - 12x - 36# = #45x^2 + 270x + 405 - 12x ... WebMar 4, 2024 · Explanation: Given: ⎧⎪ ⎨⎪⎩f (x) = x2 + 1 g(x) = 2x h(x) = x − 1. One way of thinking about these function compositions is to go back and forth between the symbols and verbal descriptions of what the functions do. In our example: f takes the square of a number and adds 1. g doubles a number. h subtracts 1 from a number.
WebWe aren't told what f is, but we do know that. f ′ ( x) = 3 x + 4. Then. f ′ ( g ( x)) = f ′ ( x 2 − 1) = 3 ( x 2 − 1) + 4 = 3 x 2 + 1. Also g ′ ( x) = ( x 2 − 1) ′ = 2 x. So, using the chain rule: [ f ( g ( x))] ′ = f ′ ( g ( x)) ⋅ g ′ ( x) = 3 x 2 + 1 ⋅ 2 x = 2 x 3 x 2 + 1. Share. WebIt is f ( x) − 1 right. So let us find f ( x) inverse. f ( x) = x 2 + 1 then f ( x) − 1 = x − 1 right [ just swipe the x with f ( x) and solve for f ( x) that should give you this result] now go to the first function g ( f ( x)) [this function is the same as g ( x 2 + 1) right.] Now find g ( x − 1) (that is g of the inverse function you ...
WebSo it's gonna be that over 1, plus the square root. One plus the square root of x squared minus one. So this is a composition f of g of x, you get this thing. This is g of f of x, … WebFree functions composition calculator - solve functions compositions step-by-step
