Two functions are given below: f(x) and h(x). State the axis of symmetry for each function and explain how to find it. f(x) = −4(x − 8)2 + 3

Step-by-step explanation:

Given quadratic function is,

f(x) = -4(x - 8)² + 3

Vertex of the parabola from the given equation is (8, 3).

Since a vertical or horizontal line through the vertex of a vertical or horizontal parabola is called as 'line of symmetry'.

x = 8 will be the line of symmetry of the function 'f'.

From the graph of second function 'h',

Vertex of the parabola → (3, 2)

Line of symmetry = Vertical line passing through vertex

x = 3 is the line of symmetry of the function 'h'.

the answer is d. 75%

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
