The graph of a quadratic function has y-intercept 10 and one of its x-intercepts is 1. The x-coordinate of the vertex of the graph is 3. The equation of the quadratic function is y = ax^2+bx+10.
a) Find the value of "a" and of "b"

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
