Answer:

1) f⁻1(x)= x+2/123

2) f(0.02235)=0.75

3) x= 0.02235

Step-by-step explanation:

part 1)

given that

f(x)=123x-2

to find F⁻1(x) we put X = f⁻1(x) in the given function to obtain

f(f⁻1(x))=123xf⁻1(x)

-> x+123x f⁻1(x)-2(f(f^-1(f⁻1(x)-x+2/123

part 2 and 3

for f(x)=0.75 we put f(x)=0.75and then solve for "x"

0.75=123 times x-2

x+0.75+2/123=0.02235
