Find the points on the graph of the function that are closest to the given point.f(x) = x2, (0, 6)
Question
Find the points on the graph of the function that are closest to the given point.
Function:
f(x) = x^2
Given Point:
(0, 6)
Solution
Sure, here are the steps to find the points on the graph of the function that are closest to the given point (0,6):
-
The function given is f(x) = x^2. The graph of this function is a parabola.
-
We are looking for the points on this graph that are closest to the point (0,6).
-
To find these points, we need to minimize the distance between the point (0,6) and any point (x, x^2) on the graph of the function.
-
The distance between these two points is given by the distance formula: sqrt((x-0)^2 + (x^2 - 6)^2).
-
To minimize this distance, we can take the derivative of the distance with respect to x, set it equal to zero, and solve for x.
-
The derivative of the distance with respect to x is: 2(x-0) + 2(x^2 - 6)(2x) = 0.
-
Solving this equation for x gives x = 0 and x = sqrt(6).
-
Substituting these values of x into the function f(x) = x^2 gives the points (0,0) and (sqrt(6), 6) on the graph of the function.
-
Therefore, the points on the graph of the function that are closest to the point (0,6) are (0,0) and (sqrt(6), 6).
