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...
In order to find the inverse function, we have to first interchange the variables x and y. After interchanging the variables, we need to solve for y. Lastly, we need to simplify.Answer and Explanation: We are given the function y=2x. We want to find the inverse of the fu...

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。
Sketch the graph of f(x)=2x+3f(x)=2x+3 and the graph of its inverse using the symmetry property of inverse functions. Show Solution Hint The graphs are symmetric about the line y=xy=x. Restricting Domains As we have seen, f(x)=x2f(x)=x2 does not have an inverse function because...
An inverse function reverses the method of a function. If, in algebra, f(x) = 2x, then inverse function of f(x) will be a function say f(y) = y/2. Graph, properties, types at BYJU’S
