So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)We say "f inverse of y"So, the inverse of f(x) = 2x+3 is written:f-1(y) = (y-3)/2...

选项 A,y = x²不是一一映射,例如当 y = 4 时,x = 2 或 x = -2,所以没有反函数。选项 B,y = |x|也不是一一映射,当 y = 2 时,x = 2 或 x = -2,没有反函数。选项 C,y = 2x 是一一映射,有反函数。选项 D,y = sinx 不是一一映射,一个 y 值对应多个 x 值,没有反函数。

What is the inverse of the function y = 3x. What is the inverse function for (2x - 3)/4? What is the inverse of the function y = 4x + 5? What is the inverse function of y = \frac{1}{3x+2} ? What is the inverse function of f(x) = (-1/2)x - 3?
Q.4. What is the inverse of the function \(f(x) = \frac{{x + 4}}{{2x – 5}}\)?Ans:Step 1: We have to substitute \(f(x)\) with \(y\):\(y = \frac{{x + 4}}{{2x – 5}}\)Step 2: We swap the variables \(x\) and \(y\):\(x = \frac{{y + 4}}{{2y ...
We use the process of implicit differentiation (which is the process of using the chain rule when the functions are implicitly defined) to derive the inverse trig derivatives.Derivative of ArcsinTo find the derivative of arcsin x, let us assume that y = arcsin x. Then by the definition of ...
