what was the production of gold in 1980?

Question

in Ghana from 1980 to 1995, the annual production of gold, G(t), I thousands of ounces can be modeled by G(t)=12t^2-103t+434, where t is the number of years since 1980.

Answer 1

Cameron,

 

What is the value of t, the number of years since 1980, for 1980?

 

Once you answer that, you can substitute that value into the expression for G(t).

 

You should be able to see the answer without doing any calculations.

 

Please let me know if you remain stuck. Thanks.

 

Michael.
