Use the graph of the function  y  = –x2  + 2x  + 8 to determine the solutions of the quadratic equation0 = –x2  + 2x  + 8.  what are the solutions of the quadratic equation0 = –x2  + 2x  + 8? –4 and 2–2 and 8–2 and 44 and 8

d

step-by-step explanation:

d

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
