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

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

42
