Given f(x) = 2x and<br> g(x) = x2+3 , find f(g(x)).

Nimfa-mama [501]

I'm assuming for g(x) you mean g(x) = x^2+3 for $g(x)=x^2+3$ .

Going with that...

$\begin{aligned}f(g(x)) &= f\left( x^2+3 \right)~~~~~\text{plug $x^2+3$ in for $x$ in $f(x)$}\\[0.5em]&= 2\cdot ( x^2+3 )~~~~~\text{so $2x$ became $2(x^2+3)$}\\[0.5em]&= 2x^2+6\endaligned}$

Just treat the enter g(x) function as a single input for f(x).

Event A is a subset of event B. P(A)=.15 and P(B)=.53 Find P(A|B). Round the answer to the nearest hundredth.

ludmilkaskok [199]

If $A\subseteq B$ , then $A\cap B=A$ . So

$\mathbb P(A\mid B)=\dfrac{\mathbb P(A\cap B)}{\mathbb P(B)}=\dfrac{\mathbb P(A)}{\mathbb P(B)}=\dfrac{0.15}{0.53}\approx0.28$
