Answer:

a(n) = -81(-4/3)^(n - 1)

Step-by-step explanation:

The first term is -81.  From -81 we obtain the next term, 108, by multiplying -81 by -4/3.  Note how (-4/3)(108) = -144 as anticipated.

Thus, the common ratio is -4/3.

The explicit function for this geometric series is

a(n) = -81(-4/3)^(n - 1)

Given that (-3,1) is on the graph of f(x), find the corresponding point for the function f(x-1)
Helen [10]

Answer:

(-2,1)

Step-by-step explanation:

So we are given f(-3)=1 since the point (-3,1) is on f(x).

We want to use this point to find a point on f(x-1).

Now,

f(-3)=1

and we want

f(x-1)=1

What would x need to be such that x-1 is -3.

x-1=-3

Add 1 on both sides:

x=-3+1

x=-2

x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.

So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).

I know that f(x-1) would only be effecting our input because x-1 is the input.

Given f(x) = x^2 – 3x – 2, what is f(5)?
miskamm [114]

Answer:

f(5)=8

Step-by-step explanation:

Given function: f(x)=x^2-3x-2

To find f(5), simply input x=5 into the function:

\begin{aligned}\implies f(5) & =5^2-3(5)-2\\& = 25-15-2\\& = 10-2\\& = 8\end{aligned}
