Answer 1

Graph is parabola

• It's quadratic function

Y inetercept is the point where the curve crosses y axis

• y inetercept is -6

X inetercepts are the points crossing x axis

• x=6,x=2

As it's parabola opening downwards vertex is maximum

• Vertex is (4,2)

So max value of y is 2

• The function is present in Q1 when x is in interval [2,6]

y≥0

Answer 2

Answer:

• quadratic function
• y-intercept:  y = -6
• x-intercepts:  x = 2 and x = 6
• y = 2, x = 4
• y ≥ 0

Step-by-step explanation:

The given graph is a parabola and so it a quadratic function.

The y-intercept is the point at which the curve crosses the y-axis.

From inspection of the graph, this is when y = -6.

The x-intercepts are the points at which the curve crosses the x-axis.

From inspection of the graph, the x-intercepts are x = 2 and x = 6.

The vertex is the turning point of the graph, so the minimum point of a parabola that opens upwards, and the maximum point of a parabola that opens downwards.

From inspection of the graph, the vertex is at (4, 2), so the greatest value of y is y = 2, and it occurs when x = 4.

The curve is above the x-axis between the interval x = 2 and x = 6.

Therefore, the function value is equal to zero or positive in this interval.

So the function value in the given interval is y ≥ 0.
