Question 1 options:

y-intercept

axis of symmetry

vertex

x-intercept

Y-intercept at (0,100).

Axis of symmetry is x = 3.

Vertex is (3,25) and

X-intercept is absent.

Step-by-step explanation:

See the given diagram.

The graph is of a parabola with the axis parallel to the positive y-axis.

The approximate position of the vertex is (3,25).

Therefore, the equation of the parabola is given by  

(x - 3)² = 4a(y - 25) (1)

Now, (6,100) point satisfies the parabola.

Therefore, from equation (1), we get

(6 - 3)² = 4a(100 - 25)

⇒ 9 = 4a(75)

⇒ a = 0.03

Hence, the equation of the parabola is (x - 3)² = 0.12(y - 25) (2)

Now, y-intercept is at x = 0.

Hence, 0.12(y - 25) = 9

⇒ y - 25 = 75

⇒ y = 100 (Appx.)

Now, x = 3 line is the axis of symmetry.

Vertex is at (3,25)

The x-intercept is absent. (Answer)
