Answer:

The circumference is approximately 125.66.

Step-by-step explanation:

The formula for circumference is 2 x 3.14(r). Radius (or r) in this case is equal to 20 since the diameter is two times the length of the radius. 40/2 = 20.

2 x 3.14(20) ≈ 125.66

State the domain and range of both the function and the inverse function. f(x) = 8 x + 8 f -1(x) = Domain of f(x): Range of f(x)
Katena32 [7]

Answer:

f^{-1}(x) = \frac{x+8}{8}

Domain of f(x): All real values.

Range of f(x): All real values.

Domain of f -1(x): All real values.

Range of f -1(x): All real values

Step-by-step explanation:

We are given the following function:

f(x) = 8x + 8

Since it is a line, we have that both the domain is the range is the real set.

Inverse function:

The domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function.

Finding the inverse function:

Exchange x and y in the original function, and isolate y. So

Original

y = 8x + 8

Exchanging:

x = 8y - 8

Isolating y:

8y = x + 8

y = \frac{x+8}{8}

f^{-1}(x) = \frac{x+8}{8}

Where would we find the point (–10,0)? A). y-axis B).quadrant ll C).x-axis D).quadrant lll
madreJ [45]
C because its not in any quadrant because the Y isn't stated so the point -10,0 is located on the X-axis
