the answer is 44 This is because when you plug in 8 for "X" the equation of f(x)=6x4 turns into f(8)=6(8)4 Which simplifies into f(8)=484Asked in Mathematics by Afreen ( 307k points)Integrate x^2 sin y dx dy, x=0 to 1, y=0 to pi;
f^(1)(x) = sqrt(x4) We have f(x) = x^24 And we seek the inverse function, f^(1)(x) My preferred approach is to put y = x^24 A And rearrange to form an explicit relationship x=f(y), and this function is the inverse, f^(1)(x) So, from A we have x^2 = y4 x = sqrt(y4) Thus f^(1)(x) = sqrt(x4) Note that by the formal definition f^(1)(x) is not aInverse\y=\frac{x}{x^26x8} inverse\f(x)=\sqrt{x3} inverse\f(x)=\cos(2x5) inverse\f(x)=\sin(3x) functioninversecalculator en Related Symbolab blog posts Functions A function basically relates an input to an output, there's an input, a Relations and Functions Class 12 MCQs Questions with Answers Question 1 Question 2 Question 3 If F R → R such that f (x) = 5x 4 then which of the following is equal to f 1 (x) Question 4 Question 5 Question 6 Question 7
