Question

Find the inverse function of f(x) = 2x +3​

Answer 1

Answer & Step-by-step explanation:

To determine f's inverse function (x)= 2x + 3, we can follow these steps:

Step 1: Replace f(x) with y: y = 2x + 3

Step 2: Solve for x in terms of y:

y = 2x + 3

y - 3 = 2x

x = (y - 3) / 2

Step 3: Replace x with f^(-1)(x):

f^(-1)(x) = (x - 3) / 2

Therefore, the inverse function of f(x) = 2x + 3 is f^(-1)(x) = (x - 3) / 2.

Hope it helps!

Answer 2

So the inverse function of f(x) = 2x + 3 is f⁻¹(x) = (x - 3) / 2.

Explanation:

To find the inverse of a function, we switch the x and y variables and solve for y. So, we start with:

y = 2x + 3

Switching x and y, we get:

x = 2y + 3

Now, we solve for y:

x - 3 = 2y

y = (x - 3) / 2

So the inverse function of f(x) = 2x + 3 is f⁻¹(x) = (x - 3) / 2.
