Please explain your answer Solution Draw a horizontal line c

Solution

Draw a horizontal line cutting the graph.. if it cuts the curve only in one point, then it is one-one function.. If the graph of a function contains a point (a, b), then the graph of the inverse relation of the function contains the point (b, a). To graph the inverse of a function, reverse the ordered pairs of the original function. Should the inverse relation of a function f (x) also be a function, this inverse function is denoted by f -1(x). \"The x- and y- coordinates switch places!\"
