Question

NO LINKS!! Please help me with this problem. Part 4a1​

Answer 1

For a reflection of parabola across x axis the rule is

• a=-a
• k=-k

Means a turns negative

So

• y=-8(x+10)²-7

Here a is -8

Turn negative

• -(-8)=8

k is -7

turn negative

• -(-7)=7

New one

• g(x)=8(x+10)²+7

Answer 2

Explanation:

Coordinates of the original down ward parabola are ( - 10, - 7 )

Coordinates of the image upward parabola are ( - 10, 7 )

g(x) = 8( x + 10 )² + 7
