7. Evaluate the function below over the domain {-1, 0,
\n" ); document.write( "1, 2}. As the values of the domain increase, do the
\n" ); document.write( "values of the function increase or decrease?
\n" ); document.write( "y = (3/4)ˣ = (3/4)(3/4)(3/4)^x
\n" ); document.write( "Since your always multiplying by 3/4, y decreases as x increases.

\n" ); document.write( "8. Suppose an investment of $5,000 doubles every 12
\n" ); document.write( "years. How much is the investment worth after 36
\n" ); document.write( "years? After 48 years?
\n" ); document.write( "Write and solve an exponential equation.
\n" ); document.write( "y = 5000*2^x
\n" ); document.write( "-------------------
\n" ); document.write( "9. Does the function represent exponential growth or
\n" ); document.write( "exponential decay? Identify the growth or decay
\n" ); document.write( "factor.
\n" ); document.write( "y = 9 ∙ (1/2)ˣ
\n" ); document.write( "Ans: decay ; 1/2
