Question

Given the function f(x) =3x^2-6x-9 is the point (1,-12) on the graph of f?

Answer 1

Answer: Yes

Explanation:

For questions like this, youve been given a value for x, and a value for y.

Plug in and see if it works out!

`3x^2- 6x - 9 = y`

`3(1)^2- 6(1) - 9 = -12` ----- Plugging in for x and y

`3 - 6 - 9 = -12`

`-12 = -12`

Since -12 is indeed equal to -12, we conclude the statement is true;

In terms of the graph, this translates to, "Yes, the point (1, -12) is on the graph of
`y = 3x^2- 6x - 9`

So your answer is Yes
