The narrowest parabola will be the one with the greatest magnitude of acceleration...y, dy/dx, d2y/dx2 for each are:

-2x^2, -4x, -4

-x^2, -2x, -2

x^2, 2x, 2 and your fourth equation is the same as the third?

From what you have the first equation, -2x^2, will be the narrowest because it has the greatest magnitude of acceleration |-4|=4

Answer:

OPTION 1

Step-by-step explanation:

You just basically plug in x and y values in all the equations and check if you get the same answer each time.

Option 1 is correct because when you plug in let's say the first coordinates,10 and 4 it does give you 6 which is right.

Or you can test it the other way, just plugging in x values and see if you get the right y value for it shown above in the table.

Hope this helps!

X+1<br> -<br> and h(x) = 4 - X, what is the value<br> Oil CD<br> Nior<br> wla<br> olo

Answer:

8/5

Step-by-step explanation:

$(g\circ h)(-3)$ means $g(h(-3))$ .

Start with the inside first: h(-3).

h(-3) means use the function called h and replace the x with -3. The expression that is called h is 4-x.

4-x evaluated at x=-3 gives us 4-(-3)=4+3=7.

So the value for h(-3) is 7, or h(-3)=7.

Now this is what we thus far:

$(g\circ h)(-3)=g(h(-3))=g(7)$ .

g(7) means use the function called g and replace x with 7. The expression that is called g is (x+1)/(x-2).

(x+1)/(x-2) evaluated at x=7 gives us (7+1)/(7-2)=(8)/(5)=8/5.

This is our final answer:

$(g\circ h)(-3)=g(h(-3))=g(7)=\frac{8}{5}$ .
