-A grasshopper is perched on a reed 5 inches above the ground. It hops off the reed and lands on the ground about 7.9 inches away. During its hop, its height is given by the equation $$h = - 0.3 x ^ { 2 } + 1.75 x + 5$$ , where x is the
Distance in inches from the base of the reed, and h is in inches. How far was the grasshopper from the base of
The reed when it was 3.25 inches above the ground? Round to the nearest tenth.

• A) 0.9 in.
• B) 6.7 in.
