Answer:
Maria is not correct.
The graph of y = 3x grows at an increasingly increasing rate, but the graph of y = 3x2 grows at a constantly increasing rate.
Therefore, the graph of y = 3x will eventually surpass the graph of y = 3x2.
Step-by-step explanation:
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.
It would be

indicating we start at 5 but do NOT include 5, and we keep going onward to positive infinity.
The curved parenthesis tells us not to include the endpoint.
2/3 is the correct answer
