Find the Ascending Area of y=(x-6)² + 4: Quadratic Function Analysis

Question

Find the ascending area of the function

y=(x6)2+4 y=(x-6)^2+4

Video Solution

Step-by-Step Solution

To solve this problem, we first note that the function is expressed in vertex form as y=(x6)2+4 y = (x-6)^2 + 4 . The vertex form of a quadratic function is y=a(xp)2+k y = a(x - p)^2 + k , where the vertex is located at (p,k) (p, k) . For our function, this vertex is at (6,4) (6, 4) .

Since the coefficient of (x6)2(x-6)^2 is positive, the parabola opens upwards. This means that the lowest point on the parabola is the vertex, making x=6 x = 6 the axis of symmetry and the point at which the function changes from decreasing to increasing.

Thus, the function is increasing on the interval where x>6 x > 6 . When x x is greater than 6, the value of y y increases as x x increases.

By examining the multiple-choice answers, we find that the choice that matches 6<x 6 < x is the correct one. Therefore, the ascending area of the function is for x>6 x > 6 .

Therefore, the solution to the problem is 6<x 6 < x .

Answer

6 < x
