Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Question 7: Is the Graph a 1-to-1?

The answer is: No

Reason: If you look at the graph, you see that when the x value is -1 the y value is -2, when x is 0, y is 0. When x is 1, y is 2, when x is 3, y is 4, and so on and so on...

Question 9: What is f(2)?

The answer is: When f (or x) is 2, y is 3... so f(2) = 3

Reason: (Look at reason for Question 7)

I hope this helped, if it did, please do not forget to give a "Thanks" and a 5 star rating...

And as always, thanks for using Brainly...

Answer:

Correct answer: Option b

Step-by-step explanation:

Distance Between Two Points

Given two points A=(ax,ay) and B=(bx,by), the distance between them can be computed by the Pythagoras's formula

$\displaystyle d=\sqrt{(bx-ax)^2+(by-ay)^2)}$

The points of the question are A(x,y) and F(0,p), thus applying the formula:

$\displaystyle d=\sqrt{(x-0)^2+(y-p)^2)}$

$\boxed{\displaystyle d=\sqrt{x^2+(y-p)^2)}}$

Correct answer: Option b
