Sharon is rowing a boat upstream. The river is flowing at a speed of 3 miles per hour. Sharon starts rowing at a speed of 8 miles per hour, but as she gets tired her speed decreases (at a rate of 1.5 miles per hour, every hour). Graph the equation that fits the description, where y represents Sharon's speed and x represents the time elapsed since the start of her workout. Question solved general 11 months ago 6192

Her work is shown. What error did Mica make?ANSWER CHOICESMica should have set each x = 0 instead of f(x).Mica should have added 2 to 3 instead of 1.Mica should have multiplied both sides by 2 instead of dividing.Mica should have subtracted 1 from both sides instead of adding.
