Question

Which function below is the inverse of f(x)= 3x+5/7

Answer 1

Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x

so

f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3
$\frac{y- \frac{5}{7} }{3}$=x
replace with f⁻¹(x)

f⁻¹(x)=$\frac{y- \frac{5}{7} }{3}$
