Use a graphing calculator to estimate the local maximum and local minimum values of the function to the nearest
hundredth.
-The polynomial $G ( x ) = - 0.006 x ^ { 4 } + 0.140 x ^ { 3 } - 0.53 x ^ { 2 } + 1.79 x$ measures the concentration of a dye in the bloodstream x seconds after it is injected. Does the concentration increase between 12 and 13 seconds?
A) No
B) Yes

Graphing the function $G(x) = -0.006x^4 + 0.140x^3 - 0.53x^2 + 1.79x$ and examining the interval between 12 and 13 seconds, the concentration of the dye in the bloodstream increases. This is because the slope of the function $G(x)$ is positive between these two points, indicating an increase in the function's value, hence an increase in concentration.
