SOLUTION: The amount of copper ore produced from a copper mine in Arizona is modeled by the function f(t)=200+32t , where t is the number of years since 2005 and f(t) is measured in thousand

Question 1136216: The amount of copper ore produced from a copper mine in Arizona is modeled by the function f(t)=200+32t , where t is the number of years since 2005 and f(t) is measured in thousands of tons.
A. What is the slope of the graph? P.S. I think maybe it is 32 but I'm probably wrong
B. At what rate is the amount of ore produced changing?(Be specific, include units)
C. How much ore had been mined by the year 2005?(Be specific, include units)

The function is of form f(t)=mt+b, linear, t-intercept b and slope m.

Slope is 32.
Value when year 2005 is for t=0; which is 200.
