Find the vertex of the function given below. y= x2 - 6x +1

(3,-10)

Step-by-step explanation:

Use the form a x 2 + b x + c , to find the values of a , b , and c . a = 1 , b = − 6 , c = − 1 Consider the vertex form of a parabola. a ( x + d ) 2 + e Find the value of d using the formula d = b 2 a . d = − 3 Find the value of e using the formula e = c − b 2 4 a . Tap for more steps... e = − 10 Substitute the values of a , d , and e into the vertex form a ( x + d ) 2 + e . ( x − 3 ) 2 − 10 Use the vertex form, y = a ( x − h ) 2 + k , to determine the values of a , h , and k . a = 1 h = 3 k = − 10 Find the vertex ( h , k ) . ( 3 , − 10 )

Step-by-step explanation:

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

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
