Find the inverse of the function f (x) = 2/5x+10

Step-by-step explanation:

f (x) = 2/5x+10

let y = f (x)

y=2/5x+10 calculate : x

2/5 x = y - 10

2x = 5 (y-10)

x = 5/2 (y-10)

x = 5/2y - 25

the inverse of the function f (x) = 2/5x+10 is : g (x) = 5/2x - 25

Answer: y=5/2x25 Step-by-step explanation: First you need to switch f (x) to y - -> y=2/5x+10 Next you swap the x's and y's - -> x=2/5y+10 Then you solve for y - -> x-10=2/5y 5x-50=2y 5/2x-25=y
