Express the function y = 2x 2 + 8x + 1 in vertex form.

- Use the form  a x ^2 + b x + c , to find the values of  a ,  b , and  c .

a = 2 ,b = − 8 , c = 1

- Consider the vertex form of a parabola.

a ( x + d ) ^2 + e

- Find the value of  d  using the formula  d = b /2a .

d=-2

- Find the value of  e  using the formula  e =c − b ^2 4 a .

e = − 7

- Substitute the values of  a ,  d , and  e  into the vertex form  a ( x + d ) 2 + e .

2 ( x − 2 ) ^2 − 7

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
