Given f(x)=2^x and g(x)=f(x-3)+4, write the new function rule (equation) for function g and describe (using words*) the two tran

miss Akunina [59]

Answer:

The first thing we do is find out what f(x-3) is
$f(x)=2^x\\f(x-3)=2^{x-3}$ this is can be simplified using the rules of exponents
$f(x-3)=2^{x-3}\\f(x-3)=2^x\div2^3\\f(x-3)=\frac{2^{x}}{8}$
Then we put that into g(x)
$g(x)=f(x-3)+4\\g(x)=\frac{2^{x}}{8}+4$
The first transformation is at f(x), where it is divided by 8, and then inserted into g(x) which increases the new transformed f(x) by 4

gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

given that on a six-question multiple-choice test there are five possible answers for each question, of which one is correct and four are incorrect

By mere guessing probability for choosing correct answer = p = 0.2

also each question is independent of the other

Hence if X is the number of correct questions then

X is binomial with p = 0.2 and n = 6

a) being correct on three questions,

= $P(X=3) = 0.08192$

(b) being correct on four questions,

= $P(X=4) = 0.01536$

(c) being correct on all six questions

= $P(x=6) = 0.000064$
