Answer:

<u>-4</u>

Step-by-step explanation:

Average rate of change (Table 1) :

A(x) = h(4) - h(1) / 4 - 1
A(x) = 9 - 3 / 4 - 1
A(x) = 6/3 = 2

Average rate of change (Table 2) :

A(x) = j(4) - j(1) / 4 - 1
A(x) = 0 - 6 / 4 - 1
A(x) = -6/3 = -2

Difference : -2 - 2 = <u>-4</u>

Car X leaves Northtown traveling at a steady rate of 55 mph. Car Y leaves 1 hour later following Car X, traveling at a steady r

Elis [28]

Unfortunately, you haven't shared the equations from which you're supposed to choose your answer.

But we can write our own.

When will the distance traveled by the 1st car = the distance traveled by the 2nd car?

55 miles + (55 mph)x = (60 mph)x

solve this for x: 55 miles = (60-55)x mph = 5 mph

x=11 hours

The two cars are the same distance from the starting point after 11 hours.

Does the table represent a exponential function x 1 2 3 4 y -1 -8 -27 -64

Setler79 [48]

Answer:

No, the given function is not an exponential function.

Step-by-step explanation:

The exponential function is defined as

$f(x)=ab^x$ .... (1)

Where a is initial value and b is growth factor.

From the given table it is noticed that the value of y decreased as the value of x increased by 1. The function is in the form of

$f(x)=-x^3$ .... (2)

$f(1)=-(1)^3=-1$

$f(2)=-(2)^3=-8$

$f(3)=-(3)^3=-27$

$f(4)=-(4)^3=-64$

The function (1) and (2) are not the same type of function.

The table represents the polynomial.

Therefore the required answer is no. The given function is not an exponential function.
