7. Convert the following function into standard form.
f(x) = –2(x – 4)2 + 6

452,489 to the nearest thousand is 452,000

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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
