Answer 1

HI!!

Answer 2

find one with a \(+1\) out at the end if you have choices

Answer 3

all of them do. lol

Answer 4

-x^2+1

Answer 5

find one with a coefficient greater than one

Answer 6

like \(2x^2+1\) or sommat

Answer 7

4x^2+1

Answer 8

x^2+1

Answer 9

0.4x^2+1

Answer 10

so far the one with the four in front

Answer 11

yeah pick \(4x^2+1\) mr X

Answer 12

can you explain how to do it?

Answer 13

lol "Mr.X"

Answer 14

it is up one, that explains the plus one out at the end

Answer 15

and it is narrower than \(x^2\) so the coefficient in front has to be larger than one

Answer 16

if it was a negative coefficient it would be flipped over the x axis
if the coefficient was less than one it would be wider

Answer 17

you can also see that \((1,5)\) is on the graph and \(4\times 1^2+1=5\)

Answer 18

ok thank you
