Identify the features of the graph

Step-by-step explanation:

On seeing the graph we find that x intercepts are 1 and 5.

Also y intercept is 5

Vertex is at (3,-4) and also parabola is open up.

The possible equations can be of the form

y =a(x-1)(x-5)

y =a(x^2-6x+5)

When x=0, y =6

Hence 6 =5a

a =6/5

Solution is

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
