It depends on what r stands for.
If r is the radius of a circle or sphere, then yes, it must be non-negative.
If r is one of the polar coordinates it can be zero, but not negative.
If r is the correlation coefficient, it can be zero or negative.

How do you find the domain and range of an exponential decay equation?
A typical formula for exponential decay is y(t) = c*exp(-r*t) , where r > 0. The domain is all reals, and the range is all positive reals, since a positive-base exponential always returns a positive value.
Why absolute value of a number is positive?
Absolute value is always the opposite of the number.
The absolute value of a number is always non negative true or false?
The absolute value will always be positive because if you think about it, the absolute value.
What is the absolute value of 0.4?
the absolute value of any number is always the positive value of that number absolute value of 0.4 = 0.4
Explain Why the product of two nonzero absolute values is always a positive number?
An absolute value must be greater or equal to zero. If the absolute value is known to be nonzero then it must be greater than zero: that is, it must be positive. The product of two (or more) positive numbers must be positive.
What is the absolute value for the positive?
the absolute value for a negative or positive value is always positive
Is the absolute value for an negative number always positive?
Yes, the absolute value for an negative number is always positive.
Why is the absolute value always positive?
It's positive by definition. That's what the absolute value is.
Can the absolute value of a number be both positive and negative Explain?
No. The absolute value of a number is always positive, or zero. The way the absolute value is defined, it can never be negative.No. The absolute value of a number is always positive, or zero.

Absolute value is always?
Absolute value is always positive. * * * * * The pedantic answer is "non-negative".
Is the absolute value of a number always positive?
Yes, always.
Why is the absolute value of a number not always positive?
Absolute value is always positive. Absolute value is the distance away from zero. Ex: |-4| = 4 |4| = 4
Is the absolute of a positive integer is a negative integer?
No. The absolute value of a number is the value of the number ignoring the sign - it is always positive: The absolute value of a negative number is a positive number; The absolute value of a positive number is a positive number.
Is the absolute value of a positive number is always a negative number is it true?
No. You have it backwards . . . . . the absolute value of a negative number is always a positive number.
How do you find the domain and range of an exponential decay equation?

Will positive numbers always have a higher absolute value than the negative numbers and WHY?
No. The absolute value is the distance a number is from zero. It is always represented by a positive number. The absolute value of any positive number and its negative counterpart is the same.
Interpret an r value of 0.92?
Strong positive correlation
