Find the inverse function of f(x) = 5x-4. Show your work.

The inverse is (x+4)/5

Step-by-step explanation:

f(x) = 5x-4

Let f(x) =y

y = 5x-4

Exchange x and y

x =5y-4

Solve for y

Add 4 to each to each side

x+4 = 5y-4+4

x+4 = 5y

Divide each side by 5

(x+4)/5 = 5y/5

(x+4)/5 =y

The inverse is (x+4)/5

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
