Question

Anwser both of these and you'll get 50 POINTS and brainliest :))

Answer 1

Answer:

1.

${x}^{2} - 8x + 7 = (x - 1)(x -7 ) \\ and \\ \frac{d}{dx} ( {x}^{2} - 8x + 7) = 0 \: or \\ 2x - 8 = 0 \implies \: x = 4$

So

Your graph will pass through 1 and 7 . And vertex will be at x = 4 .

2.

1. First draw y = x^2
2. Now draw y=(x-1)^2 or shift vertex at x=1
3. Now increase each value of y by 2 for y = (x-1)^2 + 2

So vertex will be at (1 , 2 )

For two more points put x = 0 , 2 or any other value your choice

Answer 2

Answer:

i already answered it on the first or second question
