Find the inverse of the function f(x)= 4x-2
Tju [1.3M]

Answer:

f⁻¹(x) = x/4 + 1/2

Step-by-step explanation:

To find the inverse of a function, switch the x and y variables, then isolate y.

f(x) replaced y, so you can replace it back.

y = 4x - 2

x = 4y - 2   Switched x and y

x + 2 = 4y  Added 2 to both sides

y = x/4 + 2/4    Divided both sides by 4

y = x/4 + 1/2   Simplified

f⁻¹(x) = x/4 + 1/2    Use function notation

They are not similar because BR: DB is 1:2 and KE:YK is 1:3. This is due because of the slope, the slope of KE:YK is 9/3 or 3/9 which is equal to 1:3 and the slope for BR:DB is 2/4 or 4/2 which is how you get the ratio of 1:2.
