Answer:

$3x+5$

Step-by-step explanation:

$\frac{6x^2+x-15}{2x-3}$ All I have done here is divide the polynomial by one of the factors

$\frac{\left(2x-3\right)\left(3x+5\right)}{2x-3}$ You can see you have the same equation on the top as on the bottom, 2x-3.

$(3x+5)$

Hope this helps! Have a nice day. Please mark brainliest!

These tables represent a quadratic function with a vertex at (0,3). What is the average rate of change for the interval from X =

Eva8 [605]

Answer:

-19

Step-by-step explanation:

The missing table is shown in the attachment.

Since the quadratic function has vertex at (0,3), its equation is of the form;

$y = a {x}^{2} + 3$

To find the value of 'a' we substitute any other point from the table say (1,2) to get:

$2 = a( {1)}^{2} + 3$

$a = 2 - 3 = - 1$

Hence the function is

$y = - {x}^{2} + 3$

Now

$f(10) = - 100 + 3 = - 97$

$f(9) = - 81 + 3 = - 78$

The average rate of change from x=9 to x=10 is

$\frac{f(10) - f(9)}{10 - 9} = \frac{ - 97 - - 78}{1} = - 19$

Find the average rate of change of f(x)=4x^2-6 on interval [1,a]

stiv31 [10]

9514 1404 393

Answer:

4a +4

Step-by-step explanation:

The average rate of change of f(x) on the interval is ...

(f(a) -f(1))/(a -1)

= ((4a² -6) -(4(1)² -6))/(a -1) = (4a² -4)/(a -1)

= 4(a² -1)/(a -1) = 4(a +1) = 4a +4

The average rate of change on the interval is 4a +4.
