It is 1595. Put it on excel so you can better have an overview how it is done. You need 5 columns, column A-E. On column A, put 1 to 5 in rows 1 to 5. On column C, put the answers: 2, 7, 26, 101 and 400. On column D, put number 3 in all 5 rows. Back on column B, insert =sum(C1-A1) on row 1 and copy till row 5. On column E, insert =sum(B1+C1*D1) on row 1 and copy till row 5 and you will get 1595 at the end.

Katen [24]
You don't even have to actually do the division to find the correct answer.

The leading term of q(x) is x³/x² = x, so only the 1st and 3rd selections are appropriate.

The remainder r(x)/b(x) will have the divisor as b(x), so only ...
.. the 1st selection is appropriate.

In general, the intercept of the function F(X) = a•b^x is the point
Murljashka [212]

Answer:

(0,a)

Step-by-step explanation:

Given

f(x) = ab^x

Required

Determine the intercept

The intercept is at point: x = 0

So, we have:

f(0) = ab^0

f(0) = a*1

f(0) = a

So, the intercept is at point (0,a)

<em>None of the options is true</em>
