Here, y is a cubic function of x.
When x = 3,
Hence, when x = 3, y = 126.
Answer:
Opt A. 17
Step-by-step explanation:
This is the distance between two points, which can be obtained with following equation.
Where (x2,y2)=(10,4) and (x1,y1)=(2,19)
Therefore, if we develop a little with the following:
(10-2)^2=(8)^2=64
(4-19)^2=(-15)^2=225
Evaluating that in the equation, we have: sqrt(64+125)= sqrt(289)=17
That is the distance between those points.
