What represents the inverse of the function f(x)=4x
Yuki888 [10]

Answer:

\frac{x}{4}

Step-by-step explanation:

The given function is

f(x) = 4x

As we know

f(x) = y, which implies x= f^{-1} (y)

Therefore,

y = 4x

x = \frac{y}{4}

as x= f^{-1} (y)

So,

f^{-1} (y) = \frac{y}{4}

replacing y by x in the above expression

f^{-1} (x) = \frac{x}{4}

So our inverse function is  \frac{x}{4}

Find the circumference and area of a circle with a diameter of 22 inches.
Katyanochek1 [597]

Answer:

  Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2

Step-by-step explanation:

Diameter of the circle=22\;inches

Radius=\dfrac{22}{2} =11\;inches

Circumference of a circle:

            =2\times \pi \times r

            =2\times \pi \times 11\\\\=22\pi \;inches

Area of the circle:

                  =\pi \times r^2

                 =\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2
