Showing in Function Inverses

MathWhich of the following graphs shows a function that has an inverse? (see the image for graphs)... (1 image)A function is a oneone relationship between two variables `x` and `y` ie each value of `x` is mapped to one value of `y` only. Two values of `x` may map to the same value of `y` and the relation...

Function Inversesf(x) = x^2 +4 To find the inverse of this function, swap the variables and solve for y. x = y^2 +4 y^2 + 4 = x y^2 = 4 +x y^2 = x4 Multiply each term in the equation by 1. y^2 = 4x Now...
