Question

Is this an exponential growth, decay, or linear or quadratic equation? Y=(1/2)^x+4?

Answer 1

Linear → no exponent
quadratic → highest exponent is 2
exponential growth → variable in exponent. Positive exponents have bases greater than 1. Negative exponents have bases between 1 and 0.
exponential decay → variable in exponent. Positive exponents have bases between 1 and 0. Negative exponents have bases greater than 1.

Answer 2

This equation is exponential decay

Answer 3

Thank you so much, @peachpi I appreciate the help. Would y=0.75^x be decay?

Answer 4

yes
