Find the value of x where the function is discontinuous. f(x)=x^3+3^x

1 answer:

5 0

A(x)=x^3 is a polynomial function, and polynomial functions are continuous for all x,

b(x)=3^x is an exponential function, continuous for all x.

f(x)=a(x)+b(x) is continuous because the sum of 2 continuous functions is a continuous function.

Answer: f is continuous for all x in the real numbers

A2+b2 = C2solve for a

lesantik [10]

$a^2+b*2=c^2$

$a^2+2b=c^2

$ $\text{Regroup terms}$

$a^2=c^2-2b
$ $\text{Subtract 2b from both sides}$

$a=\pm \sqrt{c^2-2b}$ $\text{Take the square root of both sides}$

Ms. Wall will roll a single number cubes. What is the probability that she will roll an even number?

Arturiano [62]

Well single number, meaning from 1 - 9. She has a higher chance of getting an odd number for sure, as there are more odd numbers on the dice :) So, the ratio is 4:5 and fraction: 4/5. %<span>44.444 is your answer :)

Thank you,
