Find the average rate of change of f(x)=2x^2-7x from x=2 to x=6
scoundrel [369]

Answer:

Step-by-step explanation:

The average rate of change of a function f between a and b (a< b) is :

R =[f(b)-f(a)] ÷ (a-b)

●●●●●●●●●●●●●●●●●●●●●●●●

Let R be the average rate of change of this function

f(6) = 2×6^2 - 7×6 = 72-42 = 30

f(2) = 2×2^2 - 7×2 = 8-14 = -6

R = [f(6) - f(2)]÷ (6-2)

R = [30-(-6)] ÷ 4

R = -36/4

R = -9

■■■■■■■■■■■■■■■■■■■■■■■■■

The average rate of change of this function is -9

Which ordered pair tells the location of the smiley face on the coordinate system?
Jet001 [13]

Answer:

(5,2)

Step-by-step explanation:

You have to look to the X axis and you'll see the smiley face 5 bars/lines across from the vertex or 0.

Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.

So all you need to do is put the numbers into (x,y) and you'll get (5,2)


Hope this helps!
