Answer:
x ≈ {-11.789, +0.501, 11.288}
Step-by-step explanation:
The cubic g(x) - f(x) = 0 has three real solutions. It can be rewritten as ...
Since the solutions are irrational, they are best found using a spreadsheet or graphing calculator. My favorite graphing calculator shows the approximate solutions below.

<em>Comment on the problem statement</em>
Your expression for f(x) is ambiguous in that many Brainly questions have the exponentiation indicator replaced by a blank: 3 x -1 often means 3^x -1 and sometimes means 3^(x-1). We have taken the expression at face value and have assumed it is a linear expression. If otherwise, the problem is basically worked the same way: write a function h(x) = g(x) - f(x) and look for solutions to h(x) = 0. Graphing can be useful.

Answer:
B and F
Step-by-step explanation:
The simple golden rule that we need to know here is
<em><u>"The probability of any event is always between 0 and 1 inclusive"</u></em>
<em><u /></em>
If an event has a probability of p(x), we can say:
Also, probability is ALWAYS POSITIVE.
Thus,
A) OK because 33.3% is 0.333, which is between 0 and 1
B) NOT OK, because probability isn't negative
C) 0.0002 is in between 0 and 1, so possible
D) 0 probability means it can't happen, so that's okay as well
E) this is a fraction with numerator less than denominator, which means its between 0 and 1, so OK
F) this fraction's numerator is greater than denominator, so it's greater than 1. Probability can't be greater than 1, so NOT OK
Out of these B and F cannot represent the probability of an event
