Hey!

Hope this helps...

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

<em>Question 7:</em>  Is the Graph a 1-to-1?

The answer is: No

<em>Reason: </em>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...


<em>Question 9:</em> What is f(2)?

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

<em>Reason:</em> (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...

What is the radius of the circle defined by x2 + 2x + y2 + 6y − 39 = 0?<br> 49<br> 9<br> 7<br> 81
Bond [772]

radius = 7

the equation of a circle in standard form is

(x-a)² + (y-b)² = r²

where (a, b) are the coordinates of the centre and r is the radius

To obtain this form ' complete the square ' on both the x and y terms

x² + 2(1)x + 1 + y² + 2(3)y + 9  = 39 + 1 + 9

(x+1)² + (y+3)² = 49 ← in standard form

with centre (1, 3) and r = √49 = 7
