Answer:

x²-8x+18

Using the vertex formula: a(x-h)²+b

we know the vertex is (4,2) which means we have

a(x-4)²+2

we need to solve for a

we know that hwne x=3 y=3 which means..

3=a(3-4)²+2

1=a(-1²)

a=1

which means our equation is

(x-4)²+2 we need to write this in standard form

to do this we carry out the exponent and get

x²-8x+16+2

which gives us

x²-8x+18
