Circumference = 2πr or πd

The formula for circumference is 2πr (2 times pi times the radius)
2r = d (The radius x 2 = the diameter), so the circumference also = πd (pi times the diameter)

The function g is related to one of the parent functions g(x) = x2 – 3 The parent function is: f(x)= x^2 Use function notation t
krek1111 [17]

g(x) is a translation of f(x), we have:

g(x) = f(x) - 3

<h3>How to write g(x) in terms of f(x)?</h3>

We have the two functions:

g(x) = x^2 - 3\\\\f(x) = x^2

We can see that g(x) is just a translation of 3 units downwards of f(x), to write g(x) in terms of f(x) we can just replace the first term by f(x):

g(x) = x^2 - 3 = f(x) - 3

So we have:

g(x) = f(x) - 3

Classify the number -61.
butalik [34]

Answer:

1. Integer, rational, and real

Step-by-step explanation:

Remember:

(This is how my teacher taught it; yours may have done it differently)

Real numbers are numbers that can be plotted on a number line.

Rational numbers can be represented as a fraction (if they can't be represented as such they are irrational).

Integers are natural numbers, the opposite of natural numbers, and zero.

Whole numbers are natural numbers and zero.

Natural numbers are numbers you can count with.

-61 fits under real numbers, rational numbers, and integers. Assuming you want to be as specific as possible, the answer will be 1. Integer, rational, and real.
