Question

Identify a, h, and k for each function.y=2(x – 4)² - 5y=(x +4)²y=-(x – 6)² +3

Answer 1

Step-by-step explanation:

The vertex form of a quadratic function is given below:

`y=a(x-h)^2+k_{}`

Part 1

In the function: y=2(x – 4)² - 5

• a=2

,

• h=4

,

• k=-5

Part 2

In the function: y=(x +4)²

We can rewrite the function as: y=(x -(-4))²+0

Therefore:

• a=1

,

• h=-4

,

• k=0

Part 3

In the function: y=-(x – 6)² +3

• a=-1

• h=6

,

• k=3
