4. What is the inverse of f(x) = 4x + 11?
A f-'(x) = 4x + 11
B f'(x) = 4x – 11
c f'(x) = *=11
D f'(x)== -11

The inverse of the function is

Explanation:

The given function is

We need to determine the inverse of the function.

Inverse of the function:

The inverse of the function can be determined by interchanging the variables x and y and then solving the function for the variable y.

Here, the function f(X) is y.

Thus, the function becomes

Interchanging the variables, we get;

Now, we shall solve the expression for the variable y.

Thus, we have,

Thus, the inverse of the function is

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
