F 4 if g x 2 x brainly
F 4 if g x 2 x brainly-In mathematics, a function (or map) f from a set X to a set Y is a rule which assigns to each element x of X a unique element y of Y, the value of f at x, such that the following conditions are met 1) For every x in X there is exactly one y in Y, the value of f at x;2) If x and y are in X, then f(x) = y;

We let g(x)= x2 and h(x) = sinx so that f(x)= g(h(x)) Then g (x) = 2x, g (h(x)) = 2sinx, and h (x) = cosx, so we have f (x) = g (h(x))h (x) = (2sinx)(cosx)= 2sinxcosx = sin2x ThePowerRule g(x) n = n g(x) n−1 g (x) Example4a Find f 4(x) if f(x)= 3 √ x x2 1 We write f(x)= (g(x)) 1 3 where g(x)= x4 x2 1 Then f (x) = 1 3 (g(x))− 2 3 g Answer is (2) g (x) = x2 x 1 g (f (x)) = 4 x2 10x 5 = (2x 2)2 (2 2x) 1 = (2 2x)2 (2 2x) 1 ⇒ f (x) = 2 2x f (5/4) = 1/2 Please log in or register to add a comment ← Prev Question Next Question →X!2 g(x) = 2(2) 0 5 = 4 5 (b) lim x!2 f(x) h(x) (c) lim x!2 f(x)h(x) g(x) Note 1 If lim x!ag(x) = 0 and lim x!af(x) = b, where bis a nite number with b6= 0, Then the values of the quotient f(x) g(x) can be made arbitrarily large in absolute value as x!aand thus 1 the limit does not exist

Find (fg)(x), (fg)(x), (f*g)(x) and (f/g)(x) for each f(x) and g(x) 2 f(x)= 8x^2 g(x)=1/x^2 I'm having trouble understanding what i have to do, please help This question is from textbook Algebra2 Answer by jim_thompson5910() (Show Source)Given f ( x) = 2 x 3 and g ( x) = – x2 5, find ( f o g ) (1) First, I'll convert this to the more intuitive form, and then I'll simplify ( f o g ) (1) = f ( g (1)) Working bitbybit, since g (1) = – (1) 2 5 = –1 5 = 4, and since f (4) = 2 (4) 3 = 8 3 = 11, then ( f o g ) (1) = f ( g (1)) = f (4) = 11The "x" is just a placeholder!

From the chain rule of composition of functions we have (fog)'(x) = f'(g(x)) g'(x) In the given problem f(g(x)) = x^2x, therefore (f(g(x))' = 2*x1 = f Transcript Example 16 Let f(x) = x2and g(x) = 2x 1 be two real functions Find (f g) (x), (f – g) (x), (fg) (x), ("f" /𝑔) (x) f(x) = x2 & g(x) = 2x 1 (fNote If f takes its values in a ring (in particular for real or complexvalued f ), there is a risk of confusion, as f n could also stand for the nfold product of f, eg f 2 (x) = f(x) f(x) For trigonometric functions, usually the latter is meant, at least for positive exponents 12
