Find the Domain c(A)^t=(1/C)a^t
Problem
Solution
Identify the independent variable in the function. In the expression
c*(A)t=1/C*at the variablet appears in the exponent, suggesting this is an exponential function oft Analyze the constraints for exponential functions. For a general exponential expression
bt the exponentt can be any real number.Check for denominators or roots. The expression
1/C*at contains a constantC in the denominator. For the expression to be defined, we must assumeC≠0 Determine the domain. Since there are no logarithms, square roots of negative numbers, or variables in the denominator that would restrict
t the variablet can take any value from negative infinity to positive infinity.State the domain in interval notation. The set of all real numbers is represented as
(−∞,∞)
