Question

Hello, I need some help with this homework question, please?HW Q23

Answer 1

Given:

`y=x^2-6x-9`

Required:

Recognition of the graph of the given equation

Step-by-step explanation:

By pitting x = 0

`y=\text{ 0}^2-6(0)-9`
`=-9`

By putting x = 1

`\begin{gathered} y=\text{ 1}^2-6(1)-9 \\ =\text{ -14} \end{gathered}`

Hence the graph cuts the y-axis at -9 for x = 0 and y = -14 for x = 1. So our required graph is the first one.

Final Answer:

Option A
