The cost, in dollars, to produce 1 watt of solar energy is a function of the number of years since 1977, `t`. From 1977 to 1987, the cost could be modeled by an exponential function `f`. Here is the graph of the function. 1. What is the statement `f\left(9\right)\approx6`saying about this situation?

HINT: f(x) = y. x is the input. y is the output. So 9 is what and 6 is what?

On a piece of paper graft y+2> -3x-3 then determine which answer matches the graph you drew
