The inverse function is obtained by interchanging corresponding values of x and y and then transposing the resulting equation to make y the subject.
f(x) = y = 8x + 5 therefore f-1(x) = x = 8y + 5 : 8y = x - 5 : y = (x - 5)/8
The inverse function of y = 8x + 5 is y = (x - 5)/8
y = 8x + 5
The inverse function is to make 'x ='
Hence
y - 5 = 8x
8x = y - 5
x = ( y - 5) / 8 The inverse function.
