Answer:

a, b – linear

c – nonlinear

Step-by-step explanation:

When classifying a function from its table, you generally are looking at the way y changes when x changes. When the x-values are evenly-spaced, as they are here, then it is much easier to identify the function type from the y-values.

For evenly-spaced x-values ...

y-values have a common difference: linear function

y-values have changing differences: non-linear

y-values have a common ratio: exponential function

y-values have common "second differences": quadratic

a) Differences of y-values are ...

11 -14 = -3, 8 -11 = -3, 5 -8 = -3 . . . linear function

b) Differences of y-values are ...

-1 -(-3) = 2, 1 -(-1) = 2, 3 -1 = 2 . . . linear function

c) Differences of y-values are ...

3 -5 = -2, 1 -3 = -2, 3 -1 = 2 . . . nonlinear function

Vadim26 [7]

You should plot the total distance traveled from the base camp on the x-coordinate while the elevation should be plotted on the y-coordinate.

<h3>What is a graph?</h3>

A graph simply refers to a type of chart which is commonly used to graphically represent data on both the vertical and horizontal lines of a cartesian coordinate (x-coordinate and y-coordinate).

<h3>How to plot this graph?</h3>

In this scenario, you would plot the total distance traveled from the base camp on the x-coordinate while the elevation of the camps would be plotted on the y-coordinate as shown in the image attached below.

EleoNora [17]

The answer to this question is false because it cannot still be both negative after you reflect over two positives.

What’s this i forgot how to do it

Mumz [18]

X and y intercepts. So x intercept is where y=0 and y intercept is where x=0. Also positive or negative meaning where y>0 (positive) and where y<0 (negative). Use these hints to do it. If you can’t then just let me know...

Determine and state the coordinates of the center and the length of the radius of the

zmey [24]

we can see that the center is (-3, 3) and the radius is 9 units.

<h3 /><h3>How to find the center and radius of the circle?</h3>

The general circle equation, for a circle with a center (a, b) and radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

Here we have the equation:

x^2 + y^2 + 6x = 6y + 63

Let's complete squares:

x^2 + y^2 + 6x - 6y = 63

(x^2 + 6x) + (y^2 - 6y) = 63

(x^2 + 2*3x) + (y^2 - 2*3y) = 63

Now we can add and subtract 9, (two times) so we get:

(x^2 + 2*3x + 9) - 9 + (x^2 - 2*3x + 9) - 9 = 63

(x + 3)^2 + (y - 3)^2 = 63 + 9 + 9 = 81 = 9^2

(x + 3)^2 + (y - 3)^2 = 9^2

Comparing with the general circle equation, we can see that the center is (-3, 3) and the radius is 9 units.
