Question

Can i have some help? subject is stretching and reflecting quadratic functions

Answer 1

#1

• (1,1) and a=5

y=ax²

• y=5(1)²
• y=5

Coordinates (1,5)

#2

• (5,25) and a=-0.6

So

• y=-0.6(5)²
• y=-0.6(25)
• y=-15

Coordinates (5,-15)

#3

• (-2,4) and a=-3

So

• y=-3(-2)²
• y=-3(4)
• y=-12

Coordinates (-2,-12)

#4

• (-4,16) and a=1/2

So

• y=1/2(-4)²
• y=16/2
• y=8

Coordinates (-4,8)

Answer 2

(5,5)

(-3,-15)

(6,-12)

(-2,8)

Explanation:

Multiply the value of "a" with the coordinates.
